Nanostructured mixed multi-metal compounds (NCM) based on nickel (Ni), cobalt (Co), and manganese (Mn) are considered as promising electrode materials owing to their multiple valence states, facile accessibility to active sites, and low activation energy for electron transfer.

Vacancy enriched NiMoO₄(V_o) nanorods have been synthesized by utilizing microwave heating. The oxygen vacancy has bought an excellent OER/HER activity and to reach 10 mA cm⁻², NiMoO₄(V_o) as anode and cathode just required 360 mV as overpotential.

NiMoO_4−x/MoO₂ hybrids with highly active Mo⁵⁺ species and atomic-level coupled nanointerfaces were synthesized as highly effective electrocatalysts for the water splitting reaction.

Metal and halogen substitution in hybrid perovskites reveals the interplay between spin–orbit coupling, structural distortions and many-body effects controlling band-gaps.

A multifunctional additive of guanidinium chloride (GuCl) in a CH₃NH₃PbI₃ perovskite absorber enabled a high open-circuit voltage of over 1.0 V for printable mesoscopic perovskite solar cells based on a TiO₂/ZrO₂/carbon architecture.

Sludge flocs (SF) from environmental waste were used to prepare high-quality N-doped mesocellular graphene foam (SF-NMGF)viaa simple one-step pyrolysis method. The SF-NMGF had a high electrocatalytic activity, operational stability and methanol-tolerance in the ORR.
