ABSTRACT
Abstract To accelerate the discovery of materials through computations and experiments, a well-established protocol closely bridging these methods is required. We introduce high-throughput screening for bimetallic catalysts that replace palladium (Pd), where similarities in electronic density states patterns were employed as descriptor. Using first-principles calculations, we screened 4350 alloy structures proposed eight candidates expected to have catalytic performance comparable Pd. Our experiments demonstrate four indeed exhibit properties those Moreover, discover (Ni-Pt) catalyst has not yet been reported H 2 O direct synthesis. In particular, Ni 61 Pt 39 outperforms prototypical Pd chemical reaction exhibits 9.5-fold enhancement cost-normalized productivity. This provides an opportunity replacement or reduction use platinum-group metals.
