“…In this regard, Ji et al reported the fabrication of cobalt nickel nitrides/g‐C 3 N 4 composite for electrochemical OER process. [ 123 ] A facile hydrothermal method was utilized to prepare these composite electrodes. This Co 2 NiN/g‐C 3 N 4 electrode exhibited an optimal electrocatalytic performance with an over potential of 0.62 V at current density of 10 mA cm −2 , which is lower than Co 2 NiN or g‐C 3 N 4 individuals.…”

Electrocatalytic and photocatalytic water splitting are effective pathways for energy conversion to overcome from the reliance on the depletion fossil fuels and preclude the severe degradation of global climate. The review begins with the basic principle and mechanisms involved in both electro/photocatalysis of water splitting. Graphitic carbon nitride (g‐C3N4) is an interesting catalyst for water splitting due to its layered conjugated metal free semiconductor, owing to its unique physicochemical characteristics. However to improve some of the features of g‐C3N4 including long term stability, large active sites, electronic band structure, low recombination rate of photogenerated charges, and many more, interface engineering with different materials have been introduced to improve the catalytic activity. The review emphasizes the basics of g‐C3N4 with its interesting properties such as chemical and thermal stability, large surface area, unique optoelectronic properties, exfoliated layered structure, and tunable surface functional groups. The various strategies that have been used to modulate catalytic activity of this material are discussed, including morphology modulation, elemental doping, interface engineering with metals, and semiconductors. Towards end of the review, a summary and future perspective is presented.

“…In the current situation of China's cobalt import and export trade, we need to understand China's position in the world cobalt trade pattern more, and the rise of the complex network analysis method facilitates better use of dynamic data to study the evolution characteristics of the world cobalt trade pattern []- [22]. As a traditional Chinese trade product in trade, cobalt trade occupies a pivotal position in Chinese product trade [23]. China's cobalt trade has a long history, and reviewing China's economic development in recent years, and it can be said that the development of the cobalt export trade economy has been a great challenge to its influence in the international market []- [26].…”

In order to enhance national competitiveness while ensuring the rational operation of world trade activities, the highly internationalized development of cobalt trade is promoted. This paper analyzes the current situation of world cobalt trade through the collection and collation of trade network data. That is, each node on the network represents an activity subject, and the relationship between nodes and nodes exists in terms of commodity demand and supply, reflecting the network Spatio-temporal divergence characteristics of global commodity trade. By measuring the topological network indicators such as density, point degree, intermediary centrality, and proximity to the center, the influence of a country in the trade network and whether it occupies the central position can be more clearly defined, effectively capturing the strength of the relationship between the nodes in the world trade network and facilitating the understanding of the evolution mechanism of the world trade network, and using the QAP regression model to calculate the relationship and trade volume between two countries that affect the trade connection. The results of the study show that China’s cobalt production in 2021 is 2,105 tons, down 8.5% year-on-year. With the passage of time, the overall scale of the international trade network of bauxite is growing, the number of countries involved in the trade is increasing, the trade volume is growing, and the trade relationship between countries is gradually increasing, which reflects the good development trend of global bauxite trade.
