Atomic-bridge structure in B-Co-P dual-active sites on boron nitride nanosheets for catalytic hydrogen generation

Engineering the adsorption and dissociation of molecules on dual-active sites at interface is an integral constituent for rational design of high-efficient catalysts. Herein, we describe a unique atomic-bridge structure in B Co-P (namely Co-B and Co-P) dual-active sites on boron nitride nanosheets to stimulate activity toward borohydride hydrolysis. The formation of atomic-bridge structure in B-Co-P dual-active sites is contributed to the Local P-inducing Strategy (LPiS). The catalyst exhibits superior kinetics (turnover frequency of 37 min(-1)) with favorable stability during ammonia borane hydrolysis. Both experimental investigation and theoretical calculations reveal the key effects of atomic-bridge structure in B-Co-P interfacial dual-active sites on tailoring the electron density of Co species and reducing the energy barrier of reaction between ammonia borane and water molecules. This discovery is anticipated to furnish an impactful strategy to rationally design novel performance oriented advanced catalysts for heterogeneous catalysis.
