What is the steel gold energy storage substrate

Are transition metal oxides a good electrocatalyst for hydrogen generation?

The results, determined both experimentally and theoretically, showed that transition metal oxides were new and great electrocatalysts for hydrogen generation. The stability of this product was over 10 h, with a Tafel slope of 46 mV per decade and an exchange current density of 0.64 mA cm−2.

How do nanoporous metal oxide-based materials improve gas sensors?

Nanoporous metal oxide-based materials are excellent in performance owing to their high specific surface area. The increased surface area improves reactive adsorption of different gases onto sensitive metal oxide layer and also the performance of the sensors.

Why are flexible energy storage and conversion devices important?

The rise of portable and wearable electronics has largely stimulated the development of flexible energy storage and conversion devices. As one of the essential parts, the electrode plays critical role in determining the device performance, which required to be highly flexible, light-weight, and conformable for flexible and wearable applications.

Can flexible materials/substrates be used to fabricate flexible energy devices?

Thus, considerable effort has been making to develop various flexible materials/substrates to fabricate flexible energy devices.

Can nanoporous metal-based supercapacitors be used for energy storage?

While they cannot be used for large-capacity energy sources like single-walled carbon nanotubes, nanoporous metal-based supercapacitors can be used for practical energy storage. It is important to develop their applications in this area by using non-noble materials in a wide range.
