Defect Engineering in Bi‐Based Photo/Electrocatalysts for Nitrogen Reduction to Ammonia

“…The Bi-based NRR catalysts currently studied are of a wide variety, including metal Bi, [28,29] BiO 2-x , [30] Bi 2 S 3 , [31] BiOX (X=F, Cl, Br and I), [32][33][34] BiVO 4 , [35] (BiO) 2 CO 3 [36] and pentavalent bismuthate M(BiO 3 ) n (n = 1, M=Li, Na, K, Ag; n = 2, M=Mg, Zn, Sr, Ba, Pb) . [37,38] Zhang et al [39] synthesized Bi nanosheets by electrochemical reduction method as NRR electrocatalyst, which showed a high Faraday efficiency of 10.46 � 1.45 % at À 0.8 V (RHE). Compared with Bi nanoparticles, the increased NRR activity of Bi nanosheets can be attributed to full exposure of edge active sites and effective p-orbital electron delocalization.…”

Synergistically Enhanced Oxidase-like Property of Core–Shell MOF Nanozymes by Decorating Au and Ag/AgCl Nanoparticles for l-Cysteine Colorimetric Sensing

“…l -Cysteine ( l -Cys) is a kind of sulfur-containing amino acid in protein tissues, which plays a role in the detoxification and protection of cells from reactive oxygen species (ROS) . Specifically, the fluctuating levels of l -Cys in human fluids would induce some disorders, such as liver damage, skin damage, hair discoloration, malabsorption syndrome, and an increased risk of Alzheimer’s and Parkinson’s disease. − Therefore, various l -Cys monitoring methods have been proposed due to their high sensitivity and specificity, including liquid chromatography, chemiluminescence, electrochemistry, and spectrophotometry. − However, some drawbacks such as time-consuming and cumbersome preparation procedures as well as expensive costs still hinder their further practical application in certain circumstances. Given the rapid reading, simplicity, and low cost, colorimetric visual analysis presents straightforward advantages …”

Controllable synthesis of BiPr composite oxide nanowires electrocatalyst for sensitive L-cysteine sensing properties

“…L-cysteine belongs to an important amino acid which is present in the proteins playing the crucial role in biological systems. L-cysteine acts as a cancer indicator, antioxidant, free radical scavenger, antitoxin and radio-protective agent [1][2][3]. L-cysteine deficiency will cause many diseases including liver damage, skin lesions, weakness, edema, hair depigmentation, muscle and fat loss, and slowed growth in children [4,5].…”
