A bi-functional Co–Ni layered double hydroxide three-dimensional porous array electrode derived from ZIF-L(Co)@ZIF-L(Co, Ni) for oxygen evolution reaction and supercapacitors

Engineering g-C3N4 composited Fe-UIO-66 to in situ generate robust single-atom Fe sites for high-performance PEMFC and Zn–air battery

“…A widely used and compromised strategy to improve the ORR performance is the high loading of Pt-based catalysts in the cathode. [4][5][6][7][8] Unfortunately, the high cost of Pt owing to its scarcity seriously hinders its large-scale production for commercialization. [9][10][11] Alternatively, scientists have turned to developing platinum group metal-free (PGM-free) catalysts with reasonable catalytic activity and durability to realize PEMFC commercialization.…”

MXene-Coated Nickel Ion-Exchanged ZIF Skeleton-Cavity Layered Double Hydroxides for Supercapacitors

“…Furthermore, the ZSC-LDH@MXene and ZSC-LDH displayed wide pore sizes with an average pore diameter of 20.5 and 17.3 nm, respectively. Accordingly, porous structures can improve the specific surface area, expose abundant electroactive sites, and facilitate electrolyte ion transport …”

“…Accordingly, porous structures can improve the specific surface area, expose abundant electroactive sites, and facilitate electrolyte ion transport. 27 XPS measurements were conducted to determine the elemental compositions and chemical states. The survey spectrum demonstrated the presence of Ni, Co, C, Ti, and O elements (Figure 3a).…”

The surface-sulphurated Co3O4 nanowire array electrocatalyst for oxygen evolution reaction and water-splitting applications

“…Nowadays, water splitting technology is widely regarded as an efficient and sustainable way of producing hydrogen. 3,4 Meanwhile, water splitting technology can also efficiently decrease energy consumption and costs of hydrogen production. Therefore, many low-cost water electrolysis devices have been developed in past studies.…”
