In addition, it has also developed a number of additional novel porous electrode. Xie [29], etc. containing a basic zeolite particles in Ni plating solution, a Ni / zeolite composite electrode prepared by electrodeposition. The composite electrode was placed 1mol / L sulfuric acid dissolution to the internal zeolite particles, to thereby obtain a porous Ni electrode. Found that many of the channels remaining after the dissolution of the zeolite roughened surface of the electrode, which greatly enhance the true surface area of an electrode, while the remaining zeolite particles also enhance the intrinsic activity of the electrode for hydrogen evolution. Weiguo [29] Preparation of other secondary oxidation method using a porous anodic aluminum oxide (AAO) template, by controlling the potential deposition assembled Ni-WP alloy nanowire arrays in the AAO template. Cathodic polarization curves and ac impedance spectroscopy (EIS) test results show, Ni-WP alloy nanowire array electrode hydrogen evolution reaction (HER) resistance is decreased, a higher activity for hydrogen evolution, current density 10 mA · cm-2 when hydrogen evolution electrode polarization potential than the alloys Ni-WP shifted about positive 250 mV.
