Solar‐driven photoelectrochemical (PEC) water splitting is a promising approach toward sustainable hydrogen (H2) generation. However, the design and synthesis of efficient semiconductor photocatalysts via a facile method remains a significant challenge, especially p‐n heterojunctions based on composite metal oxides. Herein, a MOF‐on‐MOF (metal‐organic framework) template is employed as the precursor...
Solar Hydrogen Production
In article number 2201815, Daniele Benetti, Qin Wei, Federico Rosei, and co‐workers develop a versatile template‐based metal–organic framework (MOF) method to prepare hierarchical NiO/carbon hollow nanostructures that can be used as photocathodes for solar‐driven H2 production. Compared to pure NiO‐based photocathodes, MOF‐templated NiO‐based devices exhibit improved performance...
Nickel oxide (NiO) is a promising p‐type material for a wide range of optoelectronic devices, as well as photocathode for photoelectrochemical (PEC) water splitting. However, traditional NiO photoelectrodes exhibit a wide bandgap (3.6 eV), intrinsic poor electrical conductivity, and low surface area, leading to low PEC systems performance. Herein, the authors explore a Ni‐based metal–organic framework...
