“…The band at 1578 cm −1 corresponds to the stretching mode of CN bonding in imidazole . The bands at 2926 and 3130 cm −1 are attributed to the stretching mode of CH from the aromatic ring and the aliphatic chain of the imidazole, respectively . For HS‐270, HS‐280, HS‐300, and HS‐350 samples, the bands at 575 and 664 cm −1 are characteristic vibrational peaks of Co 3 O 4 crystal.…”

Increasing the amount of active sites and enhancing their intrinsic activity are two basic strategies for designing electrocatalytic materials. [3,18] Nanostructured electrocatalytic materials have been extensively studied because of their high specific surface area. [6,9,10] Amorphous materials have also been widely explored in the field of electrocatalysis because of their specific structure and property. [19][20][21][22][23] In comparison with crystal materials, amorphous materials have the following characteristics. First, amorphous materials have long-range disorder and short-range order intrinsic structural characteristics and possess rich defects and active sites. [19][20][21][22][23][24][25] Second, the chemical composition of amorphous materials can be regulated in a wide range, [26] thereby fine tuning the electronic structure of catalysts. Third, amorphous materials possess isotropic property and can provide homogenous active sites during chemical reaction, [27] thereby favoring the regulation of reactant selectivity. Lastly, amorphous materials are usually prepared under mild conditions, which are conducive to the large-scale application of these materials. [28] Metal-organic frameworks (MOFs) are novel coordination compound materials with periodic and porous structures in which metal cations act as a coordination center and organic molecules serve as ligands. [29][30][31][32][33][34][35][36][37][38] Various MOF-derived materials, such as metal oxides, metal sulfides, and metal/carbon composites, have been prepared by heat treatment, hydrothermal/solvothermal treatment, or other treatment approaches for an MOF precursor. [39][40][41][42][43][44][45] The composition, morphological characteristics, and structure of MOF-derived materials can be effectively regulated. [39,40] MOF-derived materials can maintain the structural diversity and porosity characteristics of MOFs and effectively improve their conductivity and stability. [39,40] The structure and chemical property of MOF-derived materials can be regulated by MOF precursor design and treatment control. [39,40] Therefore, MOF-derived materials have good application prospects in electrochemical energy storage, electrochemical energy conversion, and electrochemical sensors. [46][47][48][49] As a typical representative of zeolitic imidazolate framework MOF material, ZIF-67 has been extensively studied as a precursor for derivative preparation. [50] Moreover, ZIF-67 derivatives have received more and more attentions in the field of electrocatalysis. [51][52][53][54][55][56] In the present study, an amorphous intermediate derivative was prepared using a ZIF-67 hollow sphere (HS-ZIF-67) as a precursor via low-temperature heat treatment Increasing active sites is an effective method to enhance the catalytic activity of catalysts. Amorphous materials have attracted considerable attention in catalysis because of their abundant catalytic active sites. Herein, a series of derivatives is prepared via the low-temperature heat treatment of ZIF-67 hollow sphere at ...

“…The Al foil with the thickness of 50 μm is placed on top of GOx@ZnO nanowire arrays. All exposed surface of the Al and Ti foils is uniformly coated with elastic PDMS layer for avoiding electrical leakage and short circuit [35,36]. The two electrodes are connected to the outside circuit with two copper leads (fixed with silver glue).…”

“…Typically, the presence of the membrane is expected to increase the mass transfer resistance with respect to a traditional absorption column, but superior performance of membrane contactors in terms of mass transfer coefficient have also been reported [21]. In general, porous membranes [22][23][24][25] are used in membrane contactors to minimize the impact of the membrane on the mass transfer resistance, but they usually suffer from pore wetting and the consequent increase of mass transfer resistance. Nevertheless, the problem can be prevented by using thin composite membranes, since the thin dense layer in contact with the liquid prevents penetration of liquid into the pores [26][27][28].…”
