Improving the direct synthesis of hydrogen peroxide from hydrogen and oxygen over Au-Pd/SBA-15 catalysts by selective functionalization

Recent Advances in the Direct Synthesis of H2O2

“…Hutchings and co‐workers, and others have extensively studied the synergistic effect achieved through the combination of Au and Pd. With the development of Au core‐ PdO shell nanoparticle morphology upon calcination often reported as key for improvement in catalytic selectivity, with Cybula et al.…”

“…Both Park et al . and Rodríguez‐Gómez et al . have investigated the functionalisation of SBA‐15 through the grafting of organic functional groups, with the introduction of amine groups in particular resulting in a significant enhancement in catalytic selectivtiy through the suppression of H 2 O 2 decomposition.…”

The Direct Synthesis of H2O2 Using TS‐1 Supported Catalysts

“…were the first to demonstrate that high selectivity towards H 2 O 2 can be achieved through combination of Pd with Au, with the development of a Au core‐PdO shell often reported as a key factor in the enhancement of catalytic selectivity ,. Indeed, these bimetallic Au−Pd catalysts have received significant attention by both experimentalists and theoreticians, with a combination of electronic, structural and isolation effects likely to be responsible for the synergy observed in Au−Pd systems.…”

Introduction of Ag/CuO/MCM‐48 as an efficient catalyst for the one‐pot synthesis of novel pyran‐pyrrole hybrids

“…During the past decade, bimetallic nanocatalysts have attracted the attention of many chemists. Modification of the surface electronic properties, by introduction of the second metal, could alter the intrinsic characteristics of constituent metals and improve the catalytic performance against their monometallic counterparts . Nevertheless, direct use of metallic nanoparticles suffers from some demerits in catalyst activity, stability and separation due to their aggregative nature.…”
