The electrochemical fixation of carbon dioxide (CO2) into organic halides is one the most prominent strategies for mitigating atmospheric CO2 emission, along with difficulties associated toxic and carcinogenic halogenated compounds. Cu-based nanomaterials have been explored numerous applications in nanotechnology, including electrocatalysis, catalytic transformations, photocatalysis. In this work, we designed developed a Cu-embedded carbazole-derived porous polymer (Cu@Cz-POP) nanohybrid by...

Using a catalyst-free one-pot polycondensation approach, new donor-acceptor (D-A) based porous polyimide (PeTt-POP) photocatalyst was developed. PeTt-POP produced CH4 (125.63 ppm g-1 in 6 h) from CO2 under visible light irradiation the gas-solid mode without use of co-catalysts or sacrificial agents. The progress reaction and corresponding intermediate species involved reduction were identified by operando DRIFTS experiments, which plausible mechanism proposed.

Photocatalysis is an innovative approach for producing sustainable chemicals from renewable biomass feedstock under benign conditions. Active radical intermediates are key components the photochemical conversion of upgradation; however, controlling these reactions a challenging task, especially in complex systems. In this review, we highlight current advances transformation lignocellulose to valuable chemicals, including sugars and furanic derivatives. We also describe various strategies...

We have introduced a Friedel-Crafts alkylation strategy of Ni-salphen complex as derived from 2-hydroxy-5-methoxybenzaldehyde, an isomer biomass vanillin, to construct based porous organic polymer (Ni@T-POP). The X-ray absorption spectroscopy (XAS) analysis revealed the existence Ni-N2O2 core sites in Ni@T-POP framework, which demonstrates unprecedented catalytic efficiency towards oxidative decontamination sulfur mustards (HD's) compared its precursor.

The development of efficient metal-free photocatalysts for the generation reactive oxygen species (ROS) sulfur mustard (HD) decontamination can play a vital role against stockpiling chemical warfare agents (CWAs). Herein, one novel concept is conceived by smartly choosing specific ionic monomer and donor tritopic aldehyde, which trigger linker-independent regioselective protonation/deprotonation in polymeric backbone. In this context, newly developed vinylene-linked polymers (TPA/TPD-Ionic)...
