This research intended to remove residual protein from chitin with proteases in deep eutectic solvents (DESs). The activities of some proteases in several DESs, including choline chloride/p-toluenesulfonic acid, betaine/glycerol (Bet/G), choline chloride/malic acid, choline chloride/lactic acid, and choline chloride/urea, which are capable of dissolving chitin, were tested, and only in Bet/G some proteases were found to be active, with subtilisin A, ficin, and bromelain showing higher activity than other proteases. However, the latter two proteases caused degradation of chitin molecules.

Hydrolysis of Mg-based materials is a promising technology for the development of portable hydrogen fuel cells. However, the Mg(OH) layer impedes the diffusion of water molecules into inner particles, resulting in sluggish hydrolysis performance. The hydrolysis performances of Mg-based materials (Mg, MgH, MgH-BM and MgH-RBM) with water are effectively improved under light-activation.

Hydrogen storage in metal hydrides is a promising solution for sustainable and clean energy carriers. Although Mg-based metal hydrides are considered as potential hydrogen storage media, severe surface passivation has limited their industrial application. In this study, a simple, cheap, and efficient method is proposed to produce highly reactive and air-stable bulk Mg-Ni-based hydrides by rapid treatment with water for 3 min.

As an environmentally friendly and high-density energy carrier, hydrogen has been recognized as one of the ideal alternatives for fossil fuels. One of the major challenges faced by "hydrogen economy" is the development of efficient, low-cost, safe and selective hydrogen generation from chemical storage materials. In this review, we summarize the recent advances in hydrogen production via hydrolysis and alcoholysis of light-metal-based materials, such as borohydrides, Mg-based and Al-based materials, and the highly efficient regeneration of borohydrides.

Dual-electron transfer with Mg-ion intercalation outperforms typical alkali metal-ion (Li, Na, K) systems with superior charge storage efficiency while the neutral electrolytes can achieve a working voltage beyond the hydrolysis window of 1.23 V. Hence, aqueous Mg-ion electrolytes are promising for electrochemical energy storage devices to boost the energy density and solve the safety challenges synchronously.
