Tailoring Binding Abilities by Incorporating Oxophilic Transition Metals on 3D Nanostructured Ni Arrays for Accelerated Alkaline Hydrogen Evolution Reaction

Jaerim Kim et al.

Summary: Efficient Ni-based thin film catalysts for the hydrogen evolution reaction in alkaline water electrolysis were studied by incorporating oxophilic transition metal atoms, showing a volcano relation between OH-binding energies and alkaline HER activities. The Cr-incorporated Ni catalyst exhibited optimized binding energies and enhanced HER activity in alkaline media. Introducing 3D Ni nanohelix arrays further improved catalytic performance by providing abundant surface active sites and effective channels for charge transfer and mass transport.

Efficient perovskite solar cells via improved carrier management

Jason J. Yoo et al.

Summary: Metal halide perovskite solar cells have shown great potential to disrupt the silicon solar cell market with their improved performance, yet still face limitations in light-harvesting due to charge carrier recombination. Efforts to enhance charge carrier management offer a path to increase device performance and approach the theoretical efficiency limit of PSCs.
