Dissecting Key Factors Influencing Electrochemical Conversion of Carbon Solutions over Nickel Single Atoms.

The direct electrochemical conversion of bicarbonate solutions (i.e., captured CO) has emerged as a sustainable approach for integrating CO capture and utilization compared to the traditional independent and sequential route.

3D Bombax-structured carbon nanotube sponge coupling with AgPO for tetracycline degradation under ultrasound and visible light irradiation.

A novel photocatalytic carbon nanotube sponge with three-dimensional Bombax-structure was fabricated by a facile chemical vapor deposition followed by in situ ion-exchange approach. The as-prepared sponge achieved both high-efficiency adsorption and photocatalysis towards antibiotics, which can remove up to 90% of tetracycline within an hour. The morphology and mechanism of the photocatalytic CNT sponge were explored by multiple measures.
