Published: April 11, 2024

Abstract The high toxicity, volatility, and dispersion of the light aromatics, benzene, toluene, xylene (BTX) pose a serious threat to environment human health. Compared incineration, catalytic oxidation technologies for BTX removal offer benefits such as low energy consumption, efficiency, pollution. ABO 3 –type perovskite catalysts (ABO –PCs) are particularly promising materials due their activity thermal stability, well adjustable elemental composition flexible structure allowing properties be improved. Nonetheless, full potential –PCs has yet reached. This review systematically critically analyses progress in by –PCs. Catalytic performance is assessed each category perovskite, including non–doped, doped (A–, B–, or A/B–site doped), loading type (noble metal, metal oxide, matrix composite), with structure–activity relationships established. A kinetic model proposed mechanism also presented. Finally, challenges opportunities applied other reactions highlighted.

CO2 capture and conversion have garnered worldwide attention in view of the objective sustainable development carbon neutrality. Recently, ionic liquid-functionalized metal–organic frameworks (MOFs) or covalent–organic (COFs) (MOFs/COFs) offer a rising platform for effective separation from specific gas mixture into value-added chemicals. Benefiting synergistic effect offered by ILs MOFs/COFs, IL-MOFs/COFs exhibit better exceptional adsorption/catalytic performance than pristine MOFs/COFs ILs. Herein, review intends to establish primary database recently emerging conversion, covering functionalization strategies, interaction between representative applications, aiding rational design optimization novel with properties real-world application. Along this line, different systems (CO2/N2, CO2/CH4, CO2/C2H2) further multiproducts (cyclic carbonate, hydrocarbon, alcohol, others), along mechanism insight such processes are summarized discussed. Furthermore, challenges prospects topical fields been elaborated.

Abstract Activation of small molecules is considered to be a central concern in the theoretical investigation environment‐ and energy‐related catalytic conversions. Sub‐nanostructured frustrated Lewis pairs (FLPs) have been an emerging research hotspot recent years due their advantages molecule activation. Although progress applications FLPs increasingly reported, fundamental theories related structural formation, site regulation, mechanism not yet fully developed. Given this, it attempted demonstrate underlying theory corresponding regulation methods, its activation on using CeO 2 as representative metal oxide. Specifically, this paper presents three principles for constructing surfaces, feasible engineering methods sites are presented. Furthermore, cases where typical (e.g., hydrogen, carbon dioxide, methane oxygen, etc.) activated over analyzed. Meanwhile, future challenges development FLPs‐centered The insights presented may contribute FLPs, which can potentially provide inspiration broader catalysis involving
