Recently, many researchers have been working on non-noble metal ORR catalysts suitable for Zn-Air battery (ZAB) or proton exchange membrane fuel cell (PEMFC) cathodes [37], [38], [39], while the activity and durability of catalysts are still unsatisfied under both alkaline and acidic conditio...
Highly efficient and cost-effective electro-catalysts are very much desirable if fuel cells2–4, hydrogen generation from solar and electrolytic water splitting5 and metal air battery technologies6,7 are to become ubiquitously practical on a large scale. To date, expensive noble metals based electro...
Zinc–air batteries (ZABs) are promising energy storage systems because of high theoretical energy density, safety, low cost, and abundance of zinc. However, the slow multi-step reaction of oxygen and heavy reliance on noble-metal catalysts hinder the practical applications of ZABs. Therefore, ...

This invention relates to the use of a supplemental promoter in conjunction with a noble-metal-containing catalyst comprising a carbon support in catalyzing liquid phase oxidation r
Reforming catalysts containing noble metal and zinc and reforming processCatalysts for reforming typically contain platinum supported on a high surface area alumina. During reforming reactions, specifically dehydrocyclization, such catalysts produce undesirable light gases. Applicants have found a new catalyst...
Xu et al. [81] designed and constructed an electrically modulated surface-enhanced Raman scattering (E-SERS) substrate, which is wearable and wireless, battery-free, and exhibits significantly improved detection sensitivity. They combined zinc oxide nanorods (ZnO NRs) with an asymmetric gold-...
