Nickel niobate

Nickel niobate has been examined for use as a catalyst to reduce 4-nitrophenol due to a photo-synergistic effect that exploits the synergy between thermal active sites and photogenerated electrons.^[6]

Nickel niobate has also been examined in an "open and regular" crystalline form for use as the anode in a lithium ion battery. It forms a porous, nano-scale structure that eliminates the dendrite formation that can cause short circuits and other problems. The material offers energy density of 244 mAh g−1 and retains 80%+ of its capacity across 20k cycles. The manufacturing process is straightforward and does not require a clean room.^[7] The anode offers a diffusion coefficient of 10−12 cm2 s−1 at 300 K, which allows fast charging/dischargine at high current densities, yielding capacities of 140 and 50 mAh g−1 for 10 and 100C respectively.^[8]
