AI Article Synopsis
- The study focuses on improving the electrocatalytic performance of metallene by tailoring its shape and crystal structure, specifically through the creation of hetero-phase RhB metallene (h-RhB metallene).
- The unique combination of amorphous and crystalline structures, along with the doping of non-metallic heteroatoms, enhances the electronic properties of h-RhB metallene, leading to superior performance in hydrogen production reactions.
- By utilizing a two-electrode system for water electrolysis, the h-RhB metallene achieves a notable reduction in cell voltage (0.379 V at 10 mA cm²) compared to traditional water splitting methods (1.35 V),
Article Abstract
Tailoring the morphology and crystal structure of metallene is critical to improve its electrocatalytic performance. In this work, hetero-phase RhB metallene (h-RhB metallene) with amorphous/crystalline structure is readily prepared by a two-step method. The h-RhB metallene is very unique in its non-metallic heteroatom doping and amorphous/crystalline structure. Benefiting from the unique metallene structure and the optimized electronic states induced by the incorporation of B atoms, the h-RhB metallene exhibits superior performance for hydrogen evolution reaction and hydrogen peroxide electro-oxidation reaction (HPOR). When coupled with HPOR, the h-RhB metallene||h-RhB metallene water electrolysis two-electrode system exhibits a lower cell voltage of 0.379 V (@ 10 mA cm ) compared with the overall water splitting (1.35 V). The presented synthetic method provides a powerful strategy to design metallene with hetero-phase for energy-saving H production.
