pathway (Eqs. (4) and (5)) or the Volmer-Heyrovsky pathway (Eqs. (4) and (6)), both of which involve the adsorption and desorption of Hads on electrode surface [21]. Values of b can be used to evaluate the mechanistic pathways of the HER. If Eq. (4) is the rate-determining step, b can be expected to be around 118 mV/dec. When Eq. (4) occurs rapidly and is followed by a slower electro-desorption......

continuously increased during curing. Based on the DTG curves, the mass loss of all samples can be mainly divided into three steps, corresponding to the desorption of water and the decomposition of hydration... °C can be mainly attributed to the desorption of water in the C-S-H pores and the decomposition of C-S-H gel. As temperature varied from 400 °C to 460 °C, a steep mass loss ranged from 3.1% to 17......
to the formation of oxide-free boundaries and a reduction in the thickness of the oxide, which improved the chemical activity of the Ti surface and promoted sintering densification. TiH2 exhibits high desorption kinetics, and the dehydrogenation steps should be run for enough time to complete the desorption of the hydride from the green parts. Thus, the dehydrogenation process was conducted at 715 °C for 2 h......
