Additive free, selective decomposition of formic acid to hydrogen and carbon dioxide at room temperature is still a challenging catalytic process which often requires noble metal catalyst (Pd, AuPd, AuPt) and sodium formate as an additive. Till date, catalyst design is targeted towards minimum noble metal usage along with incorporation of basic functionalities to produce in situ formate ion (key intermediate for dehydrogenation) from formic acid. In this work, we have studied the catalytic behaviour of amino silane-functionalized graphene oxide (GO) containing palladium nanoparticles for formic acid decomposition in ambient condition. By varying amine functionalization on GO and palladium content, the best performing catalyst was obtained with 5 wt% palladium loading. Additionally, it was observed for the first time that along with stability of a catalyst in reaction medium, its interaction with decomposed products, i.e., carbon dioxide with amine functional groups plays a crucial role in recyclability of a catalyst.

解读胺在氨基硅烷官能化 Pd/rGO 催化剂中的作用，用于室温下甲酸分解

在室温下无添加剂、选择性地将甲酸分解为氢气和二氧化碳仍然是一个具有挑战性的催化过程，通常需要贵金属催化剂（Pd、AuPd、AuPt）和甲酸钠作为添加剂。迄今为止，催化剂设计的目标是最大限度地减少贵金属的使用，并结合基本功能，从甲酸原位生产甲酸离子（脱氢的关键中间体）。在这项工作中，我们研究了含有钯纳米颗粒的氨基硅烷官能化氧化石墨烯 (GO) 在环境条件下对甲酸分解的催化行为。通过改变 GO 和钯含量上的胺官能化，获得了具有 5wt% 钯负载量的最佳催化剂。此外，
