Cu2O is an ideal template material for the preparation of transition metal hydroxide/oxyhydroxides with oxygen evolution reaction（OER） enhanced catalytic performance. Here, inspired by Pearson's principle, Cu2O wires were prepared and used as a sacrificial template to prepare Ni（OH）2·0.75H2O hollow tubes(Ni（OH）2HTs) with highly improved surface roughness. Benefiting from unique structural advantages, the Ni（OH）2HTs showed excellent catalytic activity, rapid kinetics and a long-term stability as the OER catalyst, where an overpotential of only 207mV was required to drive a current density of 10 mA cm-2, an ideal kinetics with a Tafel slope as 79.8 mV dec-1was calculated, and no obvious attenuation in chronoamperometry was discovered after operation for 24 h. This paper provides a novel template-assisted strategy to prepare high-performance transition metal-based OER catalysts possessing hollow and tubular structures.

Abstract: Within the lithium-ion battery sector, silicon (Si)-based anode materials have emerged as a critical driver of progress, notably in advancing energy storage capabilities. The heightened interest in Si-based anode materials can be attributed to their advantageous characteristics, which include a high theoretical specific capacity, a low delithiation potential, wide availability, and cost-effectiveness. However, these materials are not immune to challenges. One prominent issue arises from the significant volume changes that occur during lithiation (charging) and delithiation (discharging) processes, resulting in mechanical stress within the material. This stress leads to structural degradation over time, thereby reducing capacity and performance. Another critical concern revolves around the inherent low electronic conductivity of Si-based materials and their limited cycling stability, which limits their practical application on a commercial scale. This comprehensive review thoroughly examines recent advancements in SiOx (0 2 and Si-carbon composites, delving into their electrochemical properties and mechanisms. It also highlights existing challenges and suggests potential avenues for improvement, providing valuable insights for future research directions. The synthesis methods and performance benchmarks discussed in this review are essential for developing more efficient and sustainable SiOx-based anodes across various energy storage applications. © Allerton Press, Inc. 2024.
