The ideal methods for the preparation of semiconductors should be reproducible and possess the ability to control the morphology of the particles with monodispersity yields. Apart from that, it is also crucial to synthesize a large quantity of desired materials with good control of size, shape, morphology, crystallinity, composition, and surface chemistry at a reasonably low production cost. Metal oxides and chalcogenides with various morphologies and crystal structures have been obtained using different anion metal precursors (and/or different sulfur sources for chalcogenides in particular) through typical synthesis methods. Generally, spherical particles are obtained as it is thermodynamically favorable. However, by changing the anion precursor salts, the morphology of a semiconductor is influenced. Therefore, precursors having different anions show some effects on the final forms of a semiconductor. This review compiled and discussed the effects of anions (NO3−, Cl−, SO42-, CH3COO−, CH(CH3)O−, etc.) and different sources of S2- on the morphology and crystal structure of selected metal oxides and chalcogenides respectively.

The conversion of CO2 through CO2 reduction reaction (CO2RR) into valuable products has potential to lessen the greenhouse effect caused by uncontrolled CO2 emissions. Challenges of CO2RR reaction lie in the stabilization of the reaction intermediate and the activation of the inert chemical bond of CO2, but the application of CO2RR at large scale is limited by the high cost and structural instability of traditional catalysts. By applying CO2RR catalyst with delicate structure of stable CO2 intermediate to industrial production, the problems such as high cost of CO2 conversion, low catalytic selectivity and poor catalytic efficiency can be effectively solved, showing better application value and significance than traditional catalysts. This review focuses on the defects, and metal‐support interaction (MSI) effect to modify the catalyst and other strategies to enhance the effectiveness of CO2 reduction. The challenges and prospects from the three perspectives are also discussed to provide suggestions for the designing of efficient CO2RR catalysts in the future. This review offers new insights and research perspectives of reducing CO2 emission through recycling CO2, and neutralizing the carbon cycle.

“…Carbon monoxide can be used to produce synthetic liquid fuels by the Fischer–Tropsch method, which is significant to the chemical industry among ECR products . Noble metals (e.g., Pd, Au, and Ag) have been proven to be excellent electrocatalysts for their outstanding selectivity and activity for ECR. − Given that noble metals’ scarcity, high cost, and toxicity hinder their practical commercial application, achieving low-cost and efficient CO 2 conversion remains challenging. − …”

Metal heteroatom doped carbon materials display remarkable catalytic performance in the electrochemical CO 2 reduction (ECR) because the doped heteroatoms can significantly change the local density of state and electronic structure of carbon, which induces charge polarization or structural defects. Herein, we synthesized S-doped Ni II -triazolate precursors with high purity and crystallinity through a simple one-step hydrothermal method. The high-temperature pyrolysis process produced a series of Ni−S−C T (T = 800, 900, 1000 °C) materials with Ni 3 S 2 as the main component. It resulted in significant carbon structure defects in the catalyst, which increased the specific surface area and pore volume, providing a basis for improving the ECR activity. Through the structural characterizations of powder X-ray diffraction (PXRD), Raman, X-ray photoelectron (XPS), Brunauer−Emmett−Teller (BET), transmission electron microscopy (TEM), and electrochemical characterizations of linear sweep voltammetry (LSV), chronoamperometry (i−t curve), electrochemical impedance spectroscopy (EIS), and electrochemical active surface area (ECSA), as well as gaseous product analysis, we can build the structural-performance relationship. Ni−S−C T catalysts all reached the highest CO Faraday efficiency at −1.5 V vs Ag/AgCl potential, among which Ni−S−C 1000 exhibited the best catalytic activity (FE CO of 66.6% and j CO of 1.28 mA/ cm 2 ). It also displayed excellent stability and recyclability, which could realize the efficient reuse of the catalyst. In addition, the density functional theory (DFT) calculation was carried out on Ni 3 S 2 to illustrate the ECR activity origination. It is the first report on Ni 3 S 2 -based catalysts in the application of ECR.
