Abstract Graphene, an allotrope of carbon in 2D structure, has revolutionised research, development and application in various disciplines since its successful isolation 16 years ago. The single layer of sp2-hybridised carbon atoms brings with it a string of unrivalled characteristics at a fraction of the price of its competitors, including platinum, gold and silver. More recently, there has been a growing trend in the application of graphene in catalysis, either as metal-free catalysts, composite catalysts or as catalyst supports. The unique and extraordinary properties of graphene have rendered it useful in increasing the reactivity and selectivity of some reactions. Owing to its large surface area, outstanding adsorptivity and high compatibility with various functional groups, graphene is able to provide a whole new level of possibilities and flexibilities to design and synthesise fit-for-purpose graphene-based catalysts for specific applications. This review is focussed on the progress, mechanisms and challenges of graphene application in four main reactions, i.e., oxygen reduction reaction, water splitting, water treatment and Fischer–Tropsch synthesis. This review also summarises the advantages and drawbacks of graphene over other commonly used catalysts. Given the inherent nature of graphene, coupled with its recent accelerated advancement in the synthesis and modification processes, it is anticipated that the application of graphene in catalysis will grow exponentially from its current stage of infancy.

In recent years, electronic products have played an increasingly important role in modern society and have penetrated into people’s life and work. With the continuous development of technology and the increasing demand for convenience and innovation, the functions and performance of electronic products continue to improve. However, the intensification of market competition and the rapid advancement of technological progress have brought many challenges and opportunities to the field of electronic products. This paper takes the new product development project management process of Lenovo Company as the research object, adopts investigation analysis method, literature analysis method and project management theory and gateway development management theory to deeply analyze the existing problems in the new product development project management of Lenovo Company, such as: The new product development cycle is long, the new product development cost is over budget, the new product development project organization and coordination ability is weak, and the project monitoring and feedback are not timely. The causes of these problems are analyzed. In view of the existing problems, this paper makes an in-depth study of the relevant theories of project management and new product development, and puts forward an optimization scheme suitable for the improvement of the new product development project management of Lenovo Company. It means adopting agile development scheme, establishing project development cost control point, optimizing organizational structure, and establishing perfect project management supervision and feedback mechanism. Finally, based on the current situation of Lenovo ‘s new product development, this paper proposes the guarantee measures for the smooth implementation of the new product development project management optimization plan, namely, talent guarantee, development and innovation awareness, risk control awareness, and management awareness in strengthening cultural construction, so as to ensure the smooth implementation of new product development project management.
