▎ 摘　　要

NOVELTY - Preparing palladium-boron-amine-N-reduced graphene oxide (PdB/NH2-N-rGO) catalyst comprises (i) ultrasonically dispersing graphene oxide in deionized water to obtain graphene oxide suspension, (ii) adding (3-aminopropyl)triethoxysilane, sonicating and stirring to obtain amine-N-reduced graphene oxide (NH2-N-GO) suspension, (iii) adding 0.01-0.1 mol/l aqueous sodium tetrachloropalladate (Na2PdCl4) solution, and ultrasonically treating for 40-60 minutes, and (iv) adding 0.5-1.0 mol/l boron-containing reducing agent aqueous solution, stirring for 1-4 hours, washing and centrifuging. USE - The PdB/NH2-N-rGO catalyst is useful for producing hydrogen from formic acid (claimed). ADVANTAGE - The method: does not adds any stabilizer; anchors metal nanoparticles with aminosilanized graphene oxide to prepare ultra-high dispersion and controllable particle size PdB alloy catalyst; uses boron element, which modulates the electronic structure of palladium, improves the catalytic activity and selectivity of palladium; and is simple. The catalyst has high catalytic activity and stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMs are also included for: (1) preparing PdB/NH2-N-rGO catalyst by above method, where the particle size of PdB alloy in catalyst is 3.0-7.5 nm; and (2) use of PdB/NH2-N-rGO catalyst in producing hydrogen from formic acid.
