A proficient heterogeneous catalytic system for the photocatalytic N-formylation reaction of amines and cyclic carbonate synthesis from epoxides using CO2 as a carbon source under ambient conditions has been documented. sophisticated approach established current process, aiming successful production formamides carbonates with high levels selectivity efficiency by adjusting several variables such solvent, time, well light involved in reaction. We have synthesized two distinct catalysts, T-COF N-COF, along g-C3N4 heterojunction, demonstrating outstanding performance. Compared to g-C3N4@N-COF, g-C3N4@T-COF photocatalyst showed significantly better light-driven formation other suitable at room temperature. The g-C3N4@COF photocatalysts can be recycled used multiple times without any noticeable decrease efficiency.

This study addresses the pressing concern of rising paracetamol concentrations in aquatic environments through photocatalysis, an advanced oxidation process (AOP) known for its eco-friendly and cost-effective degradation harmful pollutants. We introduce a coiled flow inverter (CFI) photoreactor utilizing Co-Ni tungstate anchored on g-C3N4 (CoNiW-gCN) as photocatalyst. The CFI's helical design enhances mixing, heat, mass transfer while enabling effective irradiation with visible LED lights. includes synthesis CoNiW-gCN using CFI examines impact concentration, configuration, catalyst dose, recycle ratio efficiency. Results show over 99% 10 ppm 36 min 1 g/L dose 7.5% 4 × setup. rate was 2.7 times faster than batch reactor, offering scalable efficient method innovative technology.

Sodium-ion battery is emerging as a promising technology in the post-lithium-ion era to meet high demand for portable energy storage devices. Custom-designed organic materials have been pursued sustainable alternative electrodes sodium-ion batteries, offering solution that bypasses need traditional high-temperature synthesis. However, challenge lies achieving desired electrochemical properties through precise structural modulation and incorporation of redox-active functional groups. In this study, triptycene-based microporous ladder polymer developed featuring quinone moieties, designed an anode material high-performance batteries. The vertically aligned moieties porous prevent eclipsed stacking layers, thereby enhancing exposure electroactive sites electrolyte ions. Additionally, exhibits almost unimodal pores due its rigidity, facilitating fast Na
