Here, a sol-gel method is used to prepare a Prussian blue analogue (NiFe-PBA) precursor with a 2D network, which is further annealed to an Fe3 O4 /NiCx composite (NiFe-PBA-gel-cal), inheriting the ultrahigh specific surface area of the parent structure. When the composite is used as both anode and cathode catalyst for overall water splitting, it re...

The development of efficient and stable nonprecious-metal catalysts remains a challenge for electrochemical water oxidation in practical applications. Prussian blue analogues (MM'-PBAs, A(x)M(y) [M'(CN)(6)], -nH(2)O: A = alkali metal; M/M' = transition metals), as a kind of potential electrocatalyst candidate for oxygen evolution reaction (OER), ar...

Hollow multishelled structures(HoMSs) Co3O4 with specially appointed shell number(double-, triple- and quadruple-) were accurately prepared by a sequential templating approach. Due to the superiorities of inimitable porous multishelled structure, triple-HoMSs Co3O4 achieved the best performance among all the samples with a specific capacitance of 1...

Designing highly active, earth-abundant and robust electrocatalysts with large surface areas, abundant active sites, good electric conductivity, and minimization of gas bubble adhesion operated in the same electrolyte toward overall water splitting remains a grand challenge. Herein, we report an in situ synthesis of dendritic dicobalt phosphide (Co...
