This new catalyst comprising the optimal Co-N<sub>4<\/sub> molecules incorporated in nitrogen-doped graphene, Co<sub>1<\/sub>-NG(O), exhibits a record-high electrocatalytic reactivity, producing up to 8 times higher than the amount of H<sub>2<\/sub>O<sub>2<\/sub> that can be generated from rather expensive noble metal-based electrocatalysts.<\/p>\n<p>Just as we take a shower to wash away dirt and other particles, semiconductors also require a cleaning process. However, its cleaning goes to extremes to ensure even trace contaminants \u201cleave no trace.\u201d After all the chip fabrication materials are applied to a silicon wafer, a strict cleaning process is taken to remove residual particles. If this high-purity cleaning and particle-removal step goes wrong, electrical connections in the chip are likely to suffer from it. With ever-miniaturized gadgets on the market, the purity standards of the electronics industry reach a level equivalent to finding a needle in a desert.<\/p>\n<p>That explains why <a href=\"https:\/\/phys.org\/tags\/hydrogen+peroxide\/\" rel=\"tag\" class=\"\">hydrogen peroxide<\/a> (H<sub>2<\/sub>O<sub>2<\/sub>), a major electronic cleaning chemical, is one of the most valuable chemical feedstocks that underpins the chip-making industry. Despite the ever-growing importance of H<sub>2<\/sub>O<sub>2<\/sub>, its industry has been left with an energy-intensive and multi-step method known as the anthraquinone process. This is an environmentally unfriendly process which involves the hydrogenation step using expensive palladium catalysts. Alternatively, H<sub>2<\/sub>O<sub>2<\/sub> can be synthesized directly from H<sub>2<\/sub> and O<sub>2<\/sub> gas, although the reactivity is still very poor and it requires high pressure. Another eco-friendly method is to electrochemically reduce oxygen to H<sub>2<\/sub>O<sub>2<\/sub> a via 2-electron pathway. Recently, noble metal-based electrocatalysts (for example, Au-Pd, Pt-Hg, and Pd-Hg) have been demonstrated to show H<sub>2<\/sub>O<sub>2<\/sub> productivity although such expensive investments have seen low returns that fail to meet the scalable industry needs.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>IBS scientists and their colleagues have recently report an ultimate electrocatalyst that addresses all of the issues that trouble H2O2 production.
