In the acidic HPM solution, surface oxidation was greater and the etching rates of the GaSb and InSb surfaces increased when the solution is concentrated, which indicates that H 2 O 2 plays a key role in the surface oxidation of GaSb and InSb in acidic HPM solution. However, the GaSb and...
H2O2原位积累量决定着电-Fenton中· OH产生速率及总浓度, 但电-Fenton技术却面临着阴极H2O2积累量不足的难题.所以近些年电-Fenton技术主要围绕阴极的设计和制备展开, 即电极材料设计、修饰强化2电子ORR的电子转移(电化学过程).然而, 2电子ORR电合成H2O2不仅由电子转移控制, 还受限于氧液相传质过程.目前电-Fenton体系...
Hydrogen peroxide (H2O2) is a ubiquitous signal regulating many biological processes, including innate immunity, in all eukaryotes. However, it remains largely unknown that how transcription factors directly sense H2O2in eukaryotes. Here, we report that rice basic/helix-loop-helix transcription factor b...
As one of the top 100 chemicals in the world, hydrogen peroxide (H2O2) is a high-value green oxidant and an emerging clean liquid fuel1,2. Meanwhile, H2O2is widely used in medical sterilization, printing, bleaching, waste water treatment and other fields, which is closely related to human ...
performance in the selective 2e−ORR, producing only 0.53 mM H2O2. As the H2O2production reaction involves transfer of protons as well as electrons, the acidic media is normally more favorable15,16,17. However, PCN-NaCA-2 favors neutral to mild basic conditions for efficient solar-driven ...
Mineral nanozymes seem to be better than natural enzymes because they are cheaper, easier to transport, have variable catalytic activity, can be prepared in bulk, and can handle harsh environments like heat, acidic and basic conditions [13]. With the rise of enzymology, there are also increasing...
In the present study, we confirmed that at an acidic pH, H2O2 is not degraded by the enzymes contained in milk. This was based on documenting in newborn rats, the gastric presence of sufficient amounts of this molecule in fresh milk curds. Thus, it is reasonable to conclude that human ...

the production of H2O2in alkaline media is somewhat constrained by the following limitations: (i) the H2O2(or HO2−at a pH value above 11.6) tends to readily decompose at basic conditions18; (ii) chelating agents (e.g., ethylenediamine tetraacetic acid) are required to prevent the tramp-...
