Interfacial regulation of aqueous synthesized metal-semiconductor hetero-nanocrystals

“…Therefore, the construction of well-defined heterointerfaces is crucial for the overall application of heterostructures (Weng et al, 2014;Jang et al, 2017;Zhou et al, 2022). In the past decade, researchers have made great efforts to modulate the heterointerfaces and some low defect interfaces were fabricated by epitaxial growth with various morphologies (Bian et al, 2015;Fan et al, 2015;Jing et al, 2016;Xiong et al, 2017;Ding et al, 2022). However, Royer et al proposed the premise of epitaxial growth is that the lattice mismatch between the two different components is less than 15% (Tan et al, 2018), and the core-shell heterostructure is more demanding, which should be less than 5% (Fan et al, 2008).…”

The enhancement in the performance of ultra-small core–shell Au@AuPt nanoparticles toward HER and ORR by surface engineering

“…Pt-based catalysts are still the most potential catalysts with excellent performance toward the hydrogen evolution reaction (HER) and the oxygen reduction reaction (ORR) in acidic media. [1][2][3][4][5][6] To further boost their catalytic performance, many efforts have been made to synthesize Pt-based catalysts by controlling their sizes, [7][8][9][10][11] shapes, [12][13][14][15][16] structures, [17][18][19][20][21][22][23] and tuning surface compositions. [24][25][26][27][28][29][30] For instance, ultra-small core-shell Au-Pt nanoparticles (USCS Au@AuPt NPs) with Au-rich cores and Pt-rich shells previously reported in our work exhibit excellent electrocatalytic performance toward the HER and ORR in acidic media due to the higher electrochemically active surface area (ECSA) resulting from their small sizes and electronic effect between Pt and Au.…”

A signal-on electrochemiluminescence immunosensor for A2780 cell detection based on the excellent catalytic performance of Co2+ doped TiO2 nanodisks

“…To date, tremendous efforts have been devoted to exploring efficient ORR catalysts, such as noble metal materials and their alloy nanostructures, which have exhibited charming catalytic properties towards ORR owing to their outstanding electrical conductivity and catalytic activity. 23,24 However, the high cost and poor operational stability limit their extensive application. 25 To overcome this obstacle, alternative catalysts, including carbon materials, non-precious metals and transition metal oxides, have attracted significant interest owing to their distinctive advantages.…”
