KTH team develops new cost-effective water-splitting electrocatalyst for H2 production

Green Car Congress

Although some first-row transition metal oxides (for example, NiO x , NiFeO x , CoO x and MnO x ) had been developed as low-cost electrocatalysts for water oxidation, most of them still cannot compete with IrO 2 and RuO 2. A simple one-step hydrothermal method is employed to synthesize NiV-LDH.

GWU team demonstrates one-pot process for optimized synthesis of controlled CNTs from CO2; coupling cement and C2CNT

Green Car Congress

In 2015 we demonstrated that specific transition metals at the cathode, such as Ni, Co, Cu and Fe, act as nucleation points for high yield carbon nanotube growth in molten carbonates. Addition of up to 50 mol% Na 2 CO 3 to a Li 2 CO 3 electrolyte decreases electrolyte costs and improves conditions for intercalation in Na-ion CNT anodes.
