Light olefins are important feedstocks and platform molecules for the chemical industry. Their synthesis has been a research priority in both academia There many different approaches to of these compounds, which differ by choice raw materials, catalysts reaction conditions. The goals this review highlight most recent trends light olefin perform comparative analysis synthetic routes using several quantitative characteristics: selectivity, productivity, severity operating conditions, stability, technological maturity sustainability. Traditionally, on an industrial scale, cracking oil fractions used produce olefins. Methanol-to-olefins, alkane direct or oxidative dehydrogenation technologies have great potential short term already reached scientific maturities. Major progress should be made field methanol-mediated CO CO2 hydrogenation electrocatalytic reduction is very attractive process long run due low temperature possible use sustainable electricity. application modern concepts such as electricity-driven intensification, looping, management nanoscale catalyst design lead near future more environmentally friendly, energy efficient selective large-scale synthesis.

Continuous increase in carbon dioxide (CO2) emissions are causing imbalances the environment, which impact biodiversity and human health. The conversion of CO2 to cyclic carbonates by means metal–organic frameworks (MOFs) as a heterogeneous catalyst is prominent strategy for rectifying this imbalance. Herein, we have developed nitrogen-rich Zn (II) based framework, [Zn(CPMT)(bipy)]n (CPMT = 1-(4-carboxyphenyl)-5-mercapto-1H-tetrazole; bipy 4,4′-bipyridine), synthesized via mixed ligand strategy. This Zn-MOF showed high chemical stability both acidic basic conditions, organic solvents long time. On account concurrent presence acid–base active sites strong under abrasive was employed an effective coupling epoxides, atmospheric pressure, mild temperature, neat conditions. shows remarkable activity producing yields epichlorohydrin carbonate (98%) styrene (82%) at 70 °C 24 h reaction time, with turnover numbers (TON) 217 181, respectively. could be reused up seven cycles structural framework integrity. Overall, work demonstrates synthesis novel highly efficient MOF conversion.
