In this paper, three-dimensional (3D) hollow Ti3C2Tx MXene tubes (HTCTs) with more -O terminal groups and fewer -F groups are successfully prepared via the template-oriented electrostatic self-assembly and the subsequent annealing treatment. The obtained 3D hollow structure with large specific su...
The Co-doped MoS2 sample exhibits excellent HER activity, achieving overpotentials of 67 and 155 mV at j = 10 mA cm-2 in 1.0 M KOH and 0.5 M H2SO4, respectively. Density functional theory sim- ulations suggest that, compared with free-doping MoS2, the edged Co doping is responsible ...
The environmental consequences of chemical and analytical research, particularly the use and production of toxic reagents and solvents, have sparked widespread concern. Accordingly, the assessment of analytical techniques’ greenness is becoming increasi

Combining with scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectroscopy characterizations,it is found that the SEI film undergoes a complicated evolution process of pre-formation, self-improvement and gradual decay in succession at 25 ℃. Besides, due to the ...
