Monolayered Ni-based layered double hydroxides (LDHs) enriched with hydroxyl vacancies are syn-thesized and first applied in the methanol-assisted energy-saving hydrogen production system including independent electrolysis and photovoltaic-electrolysis. The rich hydroxyl vacancies are revealed to endow monolayered LDHs with significantly superior performance in the aspects of the activity for methanol oxidation reaction and the boosting effect for cathodic hydrogen production compared to the bulk counterparts. The theoretical and experimental results confirm that the hydroxyl vacancies can increase density of states near Fermi level of LDH (i.e. elevate electrical conductivity to form favorable charge transportation during electrocatalysis), and promote its adsorption and further cleavage for methanol, thus leading to the enhanced methanol oxidation reaction performance.(c) 2022 Elsevier Ltd.

, Chao Zhong and co‐workers report a simple, efficient, and environmentally friendly approach to achieve highly selective disinfection of specific viruses with living engineered biofilm materials from virus‐polluted water. The engineered biofilms can disinfect influenza virus from contaminated water to a level below the limit‐of‐detection for a qPCR‐based detection assay.

Skatole is a malodorous compound that contributes to the characteristic smell of animal faeces. Although skatole has long been known to originate from bacterial tryptophan fermentation, the enzyme catalysing its formation has so far remained elusive. Here we report the use of comparative genomics for the discovery of a new O2-sensitive glycyl radical enzyme catalysing the decarboxylation of indoleacetate to form skatole,

Two-dimensional (2D) layered bismuth (Bi) with a thickness-dependent direct bandgap (0-0.55 eV) has attracted ever-increasing research interest in electronics, energy storage and conversion devices. However, few-layer Bi nanosheets (NSs) are easily oxidized under ambient conditions. Searching for a convenient and low-cost strategy to produce high-quality few-layer NSs in large scale is of great importance to prompt its practical applications. Herein we report that the liquid-phase exfoliation method with acetone solvent is suitable for fabricating 2D thin and low-oxidized Bi NSs. Next, we assemble the produced Bi NSs into all-solid-state supercapacitors (ASSPs). The as-prepared devices exhibit a volumetric capacitance of 36.8 F cm(-3), together with excellent volumetric energy and power densities. The volumetric capacity can be further enhanced up to 68.7 F cm(-3)by compositing with CNTs. The maximum volumetric energy and power densities are 9.5 mW h cm(-3)and 203.2 W cm(-3), respectively. Moreover, we demonstrate that the Bi/CNT devices exhibit outstanding flexibility (79.0% retention of the initial capacitance at 180 degrees bending) and superior cycling stability (82.2% retention of the initial capacitance after 20 000 cycles), demonstrating the great potential of Bi/CNTs for high-performance flexible ASSPs.
