Electrocatalytic reduction of CO (CORR) provides a feasible way for not only CO2 conversion via tandem CO2-to-CO-to-C2+ process but also CO utilization from industrial exhaust gases. In this work, poly(ionic liquid) modified Cu catalyst (Cu@PIL) was employed as the electrocatalyst to convert low concentration CO gas to high-value C2+ products. An over 90% faradaic efficiency of C2+ products (FEC2+) was obtained at a constant current density of 125.0 mA cm–2 within a broad range of feedstock concentrations from 100.0 to 40.0 vol%. Remarkably, excellent comprehensive performance was achieved with feeding CO gas as less as 5.0 vol%, delivering a high FEC2+ of 71.1% with high CO conversion (67.4%) and high energetic efficiency (29.1%). Mechanistic studies suggest the local enrichment of CO via strong adsorption and accelerated mass transfer by porous PIL layer as well as the suppression of hydrogen evolution reaction enables the CO-to-C2+ transformation with diluted CO gas. © 2022, The Authors.

Electrocatalytic N2 and CO2 to urea by C-N coupling is an environment-friendly alternative to circumvent the Haber-Bosch process. Recent experiments have proved that bimetallic catalysts (BMC) defective configurations can be synthesized. However, diverse element combinations and unclear catalyzing mechanisms make the rational design face challenges. Herein, in-depth calculations were performed to investigate the catalytic performance of BMCs anchored on N-doped graphene. Through a proposed two-step screening strategy and investigation of the free energy of the reaction, the Ti-Co@NC catalyst exhibits an ultra-low onset potential of 0.23 V to catalyze the reaction efficiently. Furthermore, from the molecular electrostatic potential map and dual descriptor diagrams, it is identified that CO prefers to tilt-attack *N2 to promote C-N coupling effectively. The reaction process can be further enhanced by controlling the transferred electrons between two metallic sites. These results increase the C-N coupling understanding in the urea electrosynthesis and inspire the rational catalysts design. © 2022, The Authors. All rights reserved.

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

Heterogeneously catalytic depolymerization of lignin into value-added biochemicals are imperative, yet challengeable by the limited mass transport of lignin and the non-ideal spatial distributions of active sites in catalysts. Herein, a series of polycrystalline materials with Cu and Fe oxides encapsulated in hierarchical hollow nano silicalite (Cux-Fey@HhNS) were fabricated for the step-wise oxidative depolymerization of lignin into diethyl maleate (DEM). 92.0% conversion of lignin with an exceptional DEM yield of 31.2 wt.% and selectivity of 70.7% was achieved at 150 °C for 24 h using Cu2.5-Fe2.2@HhNS. This superior performance of lignin selective conversion should be attributed to the enhanced tandem processes of lignin Cα-Cβ bonds deconstruction by the framework Cu2+, and the subsequently monomers’ ring-cleavage by the isolated framework Fe3+ which is not observable in the single crystal structured catalysts. The results of catalyst characterization further revealed that the well-balanced micro-/mesoporosity ratio of Cux-Fey@HhNS facilitates the diffusion of lignin macromolecule/products, contributing to the excellent DEM yield and selectivity as well. Mechanistic investigation also illustrated that the process proceeds via a single electron transfer pathway. Therefore, this work provides new insights into lignin valorization to bulk chemicals as opposed to traditional petroleum-based routes. © 2024, The Authors. All rights reserved.

The escalating demand for refined copper has intensified research into the recycling of copper-based solid waste, exemplified by the recovery of copper from waste enameled copper wires (WECWs). Despite its potential, the pyrolysis process for WECWs is hindered by embrittlement, diminishing both recycling yield and quality. Our study pioneers the elucidation of the embrittlement mechanism during WECWs pyrolysis through atom probe tomography and first-principles calculations, revealing that hydrogen, a byproduct of paint film pyrolysis, accumulates at copper grain boundaries, inducing embrittlement by reducing adhesion energy. We introduce two innovative strategies to mitigate hydrogen-induced embrittlement: vacuum pyrolysis and enhanced N2 flow. These approaches not only significantly curb copper degradation but also achieve remarkable pyrolysis efficiencies of 92.79% and 91.4%, respectively, at temperatures 50 ºC lower than conventional methods. Our findings provide crucial theoretical insights into the embrittlement process and offer effective recovery strategies for copper from solid waste. © 2024, The Authors. All rights reserved.
