Converting CO2 into valuable chemicals is an effective way to alleviate the high level of global CO2. The cycloaddition reaction and propylene oxide (PO) has atomic economy advantage environmental friendliness compared with traditional phosgene method carbonate (PC). Due chemical inertness CO2, catalysts are needed make proceed smoothly. Through rational design, a multifunctional catalyst that combines activation sites attack PO adsorption can be formed. At same time, use harmful substances reduced by making catalytic process more environmentally friendly. In this work, we discuss research progress synthesis PC from PO. Starting mechanism, system summarized perspective design. homogeneous catalysts, focus on effect composition performance. heterogeneous heterogenization (preparation methods), including supported, confined, polymerized catalysts. addition, promising photocatalysis biomass catalysis especially introduced. Finally, in order experimental results move toward industrial production, several problems existing industrialization discussed, production equipment, influence source, product/catalyst separation.

Cyclanes serve as crucial platform compounds for the production of polymers, chemicals, and biofuels. Utilizing renewable biomass to synthesize cyclohexane is imperative not only mitigate dependence on fossil fuels but also advance green development strategies. The use metal catalysts in hydrodeoxygenation (HDO) reaction essential obtaining biomass-derived cyclanes. During HDO process, size particles adsorption capacity substrate significantly impact reaction. This study reports preparation a fine stable Ni nanoparticle material an efficient process. A postconfinement strategy was employed three-dimensional confined Ni/USY catalyst with finely dispersed particles. Initially, precursor introduced into ultrastable Y (USY) chemical microenvironment facilitate nucleation growth. Subsequently, H2 reduction within scaffold at high temperatures. Compared conventional Ni-based catalysts, these spaces restrict aggregation, resulting finer particle sizes, increased exposure active sites, enhanced catalytic activity. To understand mechanism soluble portion (SP), activity investigated using 2,2-oxydinaphthalene (ODN) lignin-related model compounds. As result, ODN completely converted decalin 160 °C under initial hydrogen pressure 2 MPa 2.5 h, while lignin (SP) dominant by cyclanes alkanes 250 8 h over Ni/USY, yield SP about 83.3%. characterization time profiles product proved that can activate H···H, which subsequently cleaves mobile H+ immobile H–. addition H···H promoted hydrogenation benzene rings removal oxygen atoms, respectively. In addition, exhibits excellent reusability after 3 runs. properties physicochemical loaded onto different kinds zeolite supports were compared used reveal reason good performance Ni/USY.
