Rapid industrialization and development have led to a tremendous increase in the use of various types plastic commodities daily life. For past several years, pollution has become global issue, posing serious threat mankind. The primary issue with increasing is lack proper management which created huge havoc environment. From initial phase waste management, been discarded, recycled, downcycled, or dumped into landfills large proportion, causing extreme damage ecosystem. Conventionally, treated via thermal processes such as pyrolysis incineration plants require amount capital and, therefore, harms aim circular economy. Chemical upcycling gaining attention high-potential catalytic strategy convert plastics, polyethylene terephthalate, polyethylene, polystyrene, etc. fuels, functionalized polymers, other value-added chemicals having direct impact on affordability viability. In this review, we focused photocatalysis, electrocatalysis, photoelectrocatalysis effective efficient technologies. These approaches can lower dependence nonrenewable resources are more environmentally friendly contrast conventional approaches.

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(6), P. 4211 - 4248

Published: March 5, 2024

Catalytic transfer hydrogenation (CTH) methodology has drawn profound attention of researchers as an economical and environmentally benign alternate to conventional method. Unlike method, CTH exhibits better reaction efficiency atom economy, it makes use simple, easily accessible, low-cost hydrogen sources. Current research on reactions is oriented toward the development non-noble-metal-based catalysts due their high abundance potential large-scale applicability. In this Review, different organic transformation reactions, such nitroarenes, nitriles, alkenes, alkynes, carbonyl compounds, hydrogenolysis, reductive amination, formylation using sources have been summarized comprehensively. addition, synthesis strategies heterogeneous structure–activity relationship involving metal–support interaction, single-atom catalysis, synergistic effect are highlighted. Furthermore, optimization parameters─such temperature, time, solvents, additives─for enhancing catalytic activity selectivity product discussed in detail. This Review provides detailed insights into recent progress made with a specific focus catalyst development, sources, mechanistic exploration.
