Highly Oriented Nitrogen‐doped Carbon Nanotube Integrated Bimetallic Cobalt Copper Organic Framework for Non‐enzymatic Electrochemical Glucose and Hydrogen Peroxide Sensor

“…022), ( 112), ( 022), ( 013), ( 222), ( 114), ( 233), ( 134), ( 044), (244), and (235) diffraction planes of MOF Co [35]. The MOF CoCu nanocubes XRD pattern is identical to that of MOF Co suggesting that the presence of copper has a marginal impact on the crystallinity [36]. Further to demonstrating the development of Cu and Co nanoparticles, the XRD pattern of NCNT MOF CoCu nanostructure is depicted in Figure 3A (d).…”

Fe3O4@N-doped carbon derived from dye wastewater flocculates as a heterogeneous catalyst for degradation of methylene blue

“…Notably, Fe 3 O 4 @NC-20 exhibited higher removal efficiency than the reference sample Fe 3 O 4 -20, indicating that the N-doped carbon matrix can improve the degradation of dye molecules via adsorption and thus accelerate the removal rate, which is consistent with the findings of previous studies. 22,44 The catalytic activity of Fe 3 O 4 @NC-20 was impressive compared with other previously reported Fe-based heterogeneous Fenton catalysts (Table S2, ESI†). The outstanding catalytic performance of Fe 3 O 4 @NC-20 demonstrated that the synergistic effect of uniform Fe 3 O 4 nanoparticles and the porous carbon matrix results in excellent MB degradation because of the resulting large surface area, high pore volume, and large number of catalytic sites.…”

“…2 The surface area of the catalyst is an essential factor in its catalytic activity. 44,45 The surface areas of the samples were investigated using N 2 adsorption-desorption isotherms (Fig. 5).…”

Cu/Co/CoS2 embedded in S,N-doped carbon as highly efficient oxygen reduction and evolution electrocatalyst for rechargeable zinc–air batteries

“…The structure formed by using carbon as substrate can effectively avoid the aggregation of metal. 37,38 Furthermore, the interaction between the metal and the N-doped C can boost the electrochemical activity.…”
