Graphene is a two-dimensional hexagonal lattice structure of carbon. It is an emergent material used for tribological owing to some exciting properties of graphene such as high thermal conductivity, excellent mechanical strength, large specific surface area, defect sites. Layered pattern provides low resistance to shear due to weakly held Van der Waal interaction which make it suitable for reducing the friction and wear in lubrication application.
Although a substantial amount of work has been reported on the performance of graphene-based nanomaterials in lubrication, challenges still exist for their practical application. For instance:
• Friction and wear are detrimental as they cause the energy and materials loss in machineries part and engine components.
• Advanced study is required on the role and mechanism of graphene-based nanomaterials.
The high friction and wear in machineries tools and engine components, lead to the wastage of a substantial amount of energy in the form of heat and frequent failure of machineries parts, In addition to this, in engine components more fuel is consumed, and cause partial combustion of fuel due to high friction and high wear. As a result, more CO2 is released to the environment. High thermal stability and conductivity, excellent mechanical properties, low shear strength, lamellar structure, and high surface area make 2D nanomaterials suitable for developing new generation lubricant and lubricant additives to reduce friction and wear.
The scope of this Research Topic is related to the society-based problem of growing environmental concerns and energy demands along with the development of energy-efficient technologies and machinery for the utilization of traditional energy sources and their solution. The rising level of greenhouse gases due to anthropogenic activities, including the combustion of fuels, coal-fired power plants, and various industrial processes, has led to global warming and air pollution. For example, in a passenger car, ~33% of fuel energy requires to overcome the friction in different parts of the engine. An effective lubricant technology in the engine could save ~17.5% of energy being utilized, which equals the global saving of 330 billion liters of fuel and reduction in 860 million tonnes of CO2 emission. A 1% friction reduction in the engine by improved lubricant technologies can annually save 1 billion liters of fuel. Owing to the importance of this Research Topic, we welcome Original Research, Review, Mini Review and Perspective articles on themes including, but are not limited to the recent and novel work in the following research areas:
• Novelty in the synthesis of graphene-based nanomaterials
• Role and mechanism of graphene-based nanomaterials for tribological/lubrication application
• Role and mechanism of graphene-based nanomaterials for wastewater treatment
• Role and mechanism of graphene-based nanomaterials for the photocatalytic CO2reduction
• Novel information obtained during characterization of the graphene-based nanomaterials
• Any relevant research work to the Research Topic
