Enhanced Pseudo-Capacitance Process in Nanoarchitectural Layered Double Hydroxide Nanoarrays Hollow Nanocages for Improved Capacitive Deionization Performance

Dun Wei et al.

Summary: In this study, a three-dimensional hollow nanocage structure of CoNi-layered double hydroxide/carbon composites was designed as a CDI anode, which effectively suppressed the self-stacking of LDH sheets and facilitated ion transport. C/CoNi-LDH exhibited a high Cl- removal capacity of 60.88 mg g(-1) and a fast Cl- removal rate of 18.09 mg g(-1) min(-1) at 1.4 V in 1000 mg L-1 NaCl solution. This study provides vital guidance for the design of high-performance electrodes for CDI.

Dual role of g-C3N4 microtubes in enhancing photocatalytic CO2 reduction of Co3O4 nanoparticles

Hui Cao et al.

Summary: This study utilizes active site and heterojunction engineering to enhance photocatalytic CO2 reduction (PCR). The results show that the g-C3N4 microtube-supported Co3O4 nanoparticle achieves a significantly high turnover number (TON) in PCR, 24-fold higher than that of pure Co3O4 and comparable to state-of-the-art photocatalysts.

Controlling metallic Co0 in ZIF-67-derived N-C/Co composite catalysts for efficient photocatalytic CO2 reduction

Fei-Fei Chen et al.

Summary: Efficient photocatalytic CO2 reduction was achieved with ZIF-67-derived-Co nanoparticles encapsulated in nitrogen-doped carbon layers (N-C/Co). Tuning the grain size and components of metallic Co-0 in the N-C/Co composite catalysts at different pyrolysis temperatures significantly impacted their photocatalytic activities, with the N-C/Co-600 sample demonstrating the best performance. The high catalytic activity, along with the magnetic properties of the Co NPs, make them promising for various applications.
