“…Therefore, it is considered as a promising electrode material Bosch et al, 2017;Shi et al, 2017;Li Y.-P. et al, 2019;Xiao et al, 2020). In recent years, since it has been noted that various processes such as thermodynamics and kinetics of various reactions occurring at the interface are significantly affected by the surface energy of micro/nanocrystals, MOF-derived materials have become a research hotspot (Yang et al, 2008;Larsson et al, 2009;Du et al, 2014Du et al, , 2017Bosch et al, 2017;Shi et al, 2017;Liu et al, 2019;Li Y.-P. et al, 2019;Xiao et al, 2020). Many studies have focused on designing and controlling their different morphologies.…”

In this paper, the Ni/NiO ultrathin nanobelts were successively synthesized by a facile in suit conversion process using pre-synthesized Ni-based metal-organic frameworks (MOFs) nanobelts as parent materials to detect the nitrite (NaNO 2 ). The synthesized Ni/NiO composites have the advantages in structure, as follows: (I) Interleaved 3D reticulated structure has strong mechanical stability; (II) Ultrathin nanobelt structures allow more active sites to be exposed and make the transfer of charge faster; (III) A large number of ultrafine Ni nanoparticles decorate the building blocks of the NiO nanobelt and enhance the electrical conductivity. Ni/NiO/GCE has an obvious oxidation peak at 0.78 V, when the concentration is between 0.5 and 1000 µM, the oxidation peak current of NaNO 2 is linearly related to the concentration, and the sensitivity is 1.5319 µA mM −1 cm −2 (S/N = 3). Moreover, the experimental results also concluded that the Ni/NiO ultrathin nanobelts not only indicated wonderful reproducibility in the determination of NaNO 2 in the pickled pork samples, but also could be well-recovered and keep stable for a long time.Keywords: in suit conversion method, Ni/NiO ultrathin nanobelt, metal nanoparticle, metal organic framework, nitrite

“…According to the type of electrolyte, it can be divided into three types: alkaline, proton exchange membrane, and solid oxide. The traditional alkaline electrolyte has low hydrogen production efficiency and large power loss, which limits its application range (Liu et al., 2019). Most proton exchange membranes use higher cost precious metals, and they will be degraded during use.…”

The hydrogen energy system based on the multi-energy complementary of renewable energy can improve the consumption of renewable energy, reduce the adverse impact on the power grid system, and has the characteristics of green, low carbon, sustainable, etc., which is currently a global research hotspot. Based on the basic principles of hydrogen production technology, this paper introduces the current hydrogen energy system topology, and summarizes the technical advantages of renewable energy complementary hydrogen production and the complementary system energy coordination forms. The problems that have been solved or reached consensus are summarized, and the current status of hydrogen energy system research at home and abroad is introduced in detail. On this basis, the key technologies of multi-energy complementation of hydrogen energy system are elaborated, especially in-depth research and discussion on coordinated control strategies, energy storage and capacity allocation, energy management, and electrolysis water hydrogen production technology. The development trend of the multi-energy complementary system and the hydrogen energy industry chain is also presented, which provides a reference for the development of hydrogen production technology and hydrogen energy utilization of the renewable energy complementary system.

“…Photocatalytic water splitting technology (PWST) offers a direct and environmentally benign approach for renewable H 2 production. [1][2][3][4] Overall water splitting into hydrogen and oxygen over semiconductors is a "Holy Grail" and a challenging task that is generally hampered by the sluggish O 2producing half reaction. To achieve efficient photocatalytic H 2 evolution, most reports have been centered on accomplishing the half reaction by adding sacrificial electron donors (such as CH 3 OH, triethanolamine, lactic acid, and ascorbic acid) to scavenge the holes, [5][6][7][8][9] while in these cases, the output values are generally less than the input values ( Figure 1a).…”

Photocatalytic water splitting technology (PWST) enables the direct use of water as appealing “liquid hydrogen source” for transfer hydrogenation reactions. Currently, the development of PWST‐based transfer hydrogenations is still in an embryonic stage. Previous reports generally centered on the rational utilization of the in situ generated H‐source (electrons) for hydrogenations, in which photogenerated holes were quenched by sacrificial reagents. Herein, the fully‐utilization of the liquid H‐source and holes during water splitting is presented for photo‐reductive N‐alkylation of nitro‐aromatic compounds. In this integrate system, H‐species in situ generated from water splitting were designed for nitroarenes reduction to produce amines, while alkanols were oxidized by holes for cascade alkylating of anilines as well as the generated secondary amines. More than 50 examples achieved with a broad range scope validate the universal applicability of this mild and sustainable coupling approach. The synthetic utility of this protocol was further demonstrated by the synthesis of existing pharmaceuticals via selective N‐alkylation of amines. This strategy based on the sustainable water splitting technology highlights a significant and promising route for selective synthesis of valuable N‐alkylated fine chemicals and pharmaceuticals from nitroarenes and amines with water and alkanols.
