Boron-doped iridium nanosheets array for energy-saving hydrogen production by hydrazine-assisted water electrolysis

Lattice engineering of noble metal-based nanomaterials via metal–nonmetal interactions for catalytic applications

“…73 In addition to the abovementioned one-pot methods, Duan et al reported a two-step method to synthesize B-doped iridium (Ir) nanosheets (IrB NSs) supported on nickel (Ni) foam by using NaBH 4 as the B source. 74 Ir NSs on the Ni foam support were first prepared by reducing IrCl 3 . The Ir NSs/Ni form was then boronized in NaBH 4 -H 2 O solution in an ice bath for 5 h. After B doping, lattice spacing on the (111) f crystal plane of IrB NSs was 0.225 nm, larger than that of pure Ir (0.218 nm) (Fig.…”

Enhancing oxygen evolution reactions in nanoporous high-entropy catalysts using boron and phosphorus additives

“…Previous studies have shown that excess electrons in noble elements effectively weaken the bonding between O and Ir, reduce the binding energy, and boost the catalytic activity of Ir–B. 43…”

NiFeP nanosheets for efficient and durable hydrazine-assisted electrolytic hydrogen production

“…As a green, highly energy-dense energy carrier, hydrogen has become one of the most attractive alternatives to traditional fossil fuels. 1–4 At present, hydrogen is mainly derived from the chlor-alkali waste gas and coke oven gas by adsorption or the reforming of petrochemical waste gas. 5 Water electrolysis is considered to be one of the most effective and cleanest hydrogen production methods in the field of renewable energy, and it is more convenient than traditional hydrogen production methods.…”
