High Yield Silica-Based Emerging Nanoparticles Activities for Hybrid Catalyst Applications

Today is the era of catalysis, which has a spectacular range of influence in every field of research as they brought about many exciting developments. Among the varieties of catalysts studied, nanocatalysts, in particular, have grabbed the attention of many researchers worldwide since they facilitate environmentally sustainable catalytic processes. Currently, hybrid nanocatalysts made up of organic-inorganic nanomaterials are used for various transformation reactions. Including this, a remarkable number of reports in the literature describe the use of silica N.P.s as solid support for the fabrication of hybrid nanocatalysts. Because of its high natural abundance, unique chemical and physical properties, and easy synthesis and separation, it is considered a promising candidate for the immobilization process. Moreover, it can be used in the bare form and as solid support material for the active catalytic species' adsorption, enhancing the nanocatalysts' stability, reactivity, selectivity, recovery, and recyclability. Through this review, the authors attempt to briefly summarize the recent progress made by the heterogeneous Si-based hybrid nanaocatalysts in developing a diverse range of transformation reactions, including coupling, oxidation, reduction multicomponent reaction, and CO2 conversion.
