Immobilized BiCl3@Bi@g-C3N4 on one-dimensional multi-channel carbon fibers as heterogeneous catalyst for efficient CO2 cycloaddition reaction

Abstract

A novel heterogeneous catalyst (BBCNC), where the Bi, BiCl₃ and g-C₃N₄ were deposited on one-dimensional multi-channel carbon fibers (CNFs), was developed and characterized. And it was found that Bi³⁺ could be reduced to Bi by the substance from the thermal polycondensation of melamine and the carrier CNFs. The Lewis acid and base sites enabled a synergistically catalytic cycloaddition reaction of CO₂ with high catalytic conversion and selectivity.
