With the increasingly serious greenhouse effect, electrochemical carbon dioxide reduction reaction (CO2RR) has garnered widespread attention as it is capable of leveraging renewable energy to convert CO2 into value-added chemicals and fuels. However, performance CO2RR can hardly meet expectations because diverse intermediates complicated processes, necessitating exploitation highly efficient catalysts. In recent years, with advanced characterization technologies theoretical simulations,...
Abstract The controlled synthesis of metal nanomaterials with unconventional phases is significant importance to develop high‐performance catalysts for various applications. However, it remains challenging modulate the atomic arrangements nanomaterials, especially alloy nanostructures that involve different metals distinct redox potentials. Here we report general one‐pot IrNi, IrRhNi and IrFeNi nanobranches hexagonal close‐packed (hcp) phase. Notably, as‐synthesized hcp IrNi demonstrate...
Abstract Electrochemical nitrate reduction reaction (NO 3 RR) is emerging as a promising strategy for removal and ammonia (NH ) production using renewable electricity. Although great progresses have been achieved, the crystal phase effect of electrocatalysts on NO RR remains rarely explored.

IrNiCu@Cu‐20 shows superior catalytic performance,...
Prussian blue analogs (PBAs), as a classical kind of microporous materials, have attracted substantial interests considering their well-defined framework structures, unique physicochemical properties and low cost. However, PBAs typically adopt cubic structure that features small pore size specific surface area, which greatly limits practical applications in various fields ranging from gas adsorption/separation to energy conversion/storage biomedical treatments. Here we report the facile...
Phase control provides a promising approach for physicochemical property modulation of metal/alloy nanomaterials towards various electrocatalytic applications. However, the controlled synthesis alloy with unconventional phase remains challenging, especially those containing both p‐ and d‐block metals. Here, we report one‐pot ultrathin RhSb nanoflowers an 2H phase. Using as electrocatalyst nitrite reduction reaction in neutral media, optimal NH3 Faradaic efficiency yield rate can reach up to...
