Electrochemical detection of nitrate with carbon nanofibers and copper co-modified carbon fiber electrodes

NiTe2 Nanosheets for Broadband Photodetection

“…XPS measurements were carried out to investigate the valence state of the NiTe 2 . In the survey XPS spectrum (Figure S2a), typical constituents of Ni and Te besides contaminated C and O were detected. , The peak at 283.7 eV is ascribable to the C 1s binding energy, which is useful for energy calibration. The signals of Ni 2p 3/2 (∼854.9 eV) and 2p 1/2 (∼872.9 eV) are attributed to Ni 4+ (Figure S2b), while the peaks at ∼572.2 and 582.6 eV can be assigned to Te 2– (Figure S2c).…”

Lattice-disorder layer generation from liquid processing at room temperature with boosted nanointerface exposure toward water splitting

“…Endowing MCHs with high durability can be achieved by surface microenvironment engineering to provide more active sites, facilitated mass diffusion and multicomponent nano-interface building. [21][22][23][24][25] One method for constructing a supercial nanostructure is to deploy or grow another zero/one/two/three-dimensional structure on the surface of existing substances. 26,27 In situ surface transformation of cobalt carbonate hydroxides (CCH) into CCH@Co-Pi by Cui et al achieved high turnover frequency and long-term electrochemical stability.…”

Iridium-decorated carbon nanotubes as cathode catalysts for Li-CO2 batteries with a highly efficient direct Li2CO3 formation/decomposition capability

“…Tremendous efforts have been paid to explore a wide range of various catalysts, such as carbon-based materials [25,26] , metals [27,28] , metal oxides [29,30] and metal boride [31] with high electrocatalytic activity for LCBs. Among them, N-doping carbon supported noble metals [32,33] have been considered as promising candidate catalysts for LCBs. Zhou et al utilized porous three-dimensional carbon nanotubes (CNTs) as the cathode catalysts, which delivered a discharge specific capacity of 6000 mAh g −1 at 100 mA g −1 and run for 22 cycles at 100 mA g −1 with the fixed capacity of 1000 mAh g −1 [34] .…”
