The synergistic effect of NiCo nanoparticles and metal organic framework: Enhancing the oxygen evolution reaction of carbon nanohorn-based catalysts

Toward Developing Superior Cu-Based Metal–Organic Framework-Derived Materials for Electrocatalytic Oxidation of Ethanol

“…The relative increase in carbon content is consistent with the production of carbonized materials, which may improve the material conductivity. 60,61 Strangely, with the increase of Zn doping, the extent of surface roughening was minimized. Moreover, the migration of Cu was absent over the Cu 0.2 Zn 0.8 @C material, possibly due to its lower content.…”

“…This observation underscores the necessity for an effective postprocessing strategy, such as pyrolysis. 26,49,60,61 Next, we performed the same set of electrocatalytic oxidation reactions (including EOR, MOR, and OER) over postpyrolysis Cu x Zn y @C materials (Figures 5, S4−S8). Similarly, we compared the potentials of the self-supporting Cu x Zn y @C electrodes for current densities of 10, 50, and 100 mA cm −2 (Figure 5a).…”

l-Lysine-induced green synthesis of CoS/Co3O4 nanoframes for efficient electrocatalytic oxygen evolution

“…34–40 However, the synthesis of CoS/Co 3 O 4 nanoframes still faces great limitations because most of the synthesis is still time-consuming, labor-intensive, and not green. 41–44…”

“…[34][35][36][37][38][39][40] However, the synthesis of CoS/Co 3 O 4 nanoframes still faces great limitations because most of the synthesis is still timeconsuming, labor-intensive, and not green. [41][42][43][44] Amino acid molecule-induced strategies have shown great potential in research on controlled and green synthesis of catalysts, due to the following advantages: (i) amino acids have good biocompatibility and are inherently green and non-toxic and rarely hazardous to the environment during synthesis of the catalyst, which is conducive to the construction of green synthesis routes; 45,46 (ii) amino acids contain abundant functional groups that can effectively coordinate with metal ions, and their coordination ability can also be regulated by simply adjusting the pH value of the solution, thereby affecting the nucleation and growth orientation of the catalyst; 47,48 and (iii) specific types of amino acids can be selected to induce the synthesis of catalysts with specific structures, which is beneficial for improving the purity and quality of the catalyst and decreasing the experimental difficulty. 49,50 However, at present, amino acid molecules are mainly used in the morphology regulation of noble-metal-based catalysts, and there are few reports on amino acids as morphology regulators of non-noble metal-based catalysts.…”

Biologically and Catalytically Active Cubic Silver Chloride- anchored Palladium/Gold Bimetallic Nanomaterials

“…The physical and chemical characteristics of bi-and tri-metallic NPs differ from those of mono-metallic NPs, including changes in optical and electrical properties that vary with size and composition [8]. Bi-and tri-metallic nanoparticles have seen a rise in use over the last decade for a variety of catalytic applications, including water splitting [9,10], formic acid [11], ethanol [12], methane [13], methanol [8] oxidation, H 2 O 2 synthesis [14], and nitroarenes reduction [15]. Bi-and tri-metallic NPs can now be synthesized using various physical methods, including laser ablation [16], anodic dissolution [17], and chemical methods such as co-reduction [18], sol-gel [19], and seeded growth [20].…”
