“…NOx plays an important role in acid rain formation, diseases and photochemistry. Therefore, the elimination of NOx is a hot topic in the area of environmental protection [258][259][260][261]. The photocatalytic oxidation of NO to NO 2 is a good way to remove NO from flue gas, as NO 2 can be removed simply by reacting with hydrocarbons to release N 2 or water [262].…”

Photocatalysis is a classical solution to energy conversion and environmental pollution control problems. In photocatalysis, the development and exploration of new visible light catalysts and their synthesis and modification strategies are crucial. It is also essential to understand the mechanism of these reactions in the various reaction media. Recently, bismuth and graphene’s unique geometrical and electronic properties have attracted considerable attention in photocatalysis. This review summarizes bismuth-graphene nanohybrids’ synthetic processes with various design considerations, fundamental mechanisms of action, heterogeneous photocatalysis, benefits, and challenges. Some key applications in energy conversion and environmental pollution control are discussed, such as CO2 reduction, water splitting, pollutant degradation, disinfection, and organic transformations. The detailed perspective of bismuth-graphene nanohybrids’ applications in various research fields presented herein should be of equal interest to academic and industrial scientists.

“…Secondly, there is fuel NOx. This is nitrogen bound to organic compounds in the fuel that reacts with oxygen [12,13]. The reaction mechanism is quite complex and there is still considerable uncertainty about the exact reaction mechanism.…”

“…Lastly, there is prompt NOx, which is formed by the reaction of atmospheric nitrogen with radicals formed during combustion. The contribution of the latter is disputed in literature [13], but most research considers the concentration of prompt NOx as very low. NOx reacts with moisture, thus forming nitric acids, and it reacts with volatile organic compounds, thus producing ozone.…”

Air quality currently poses a major risk to human health worldwide. Transportation is one of the principal contributors to air pollution due to the quality of exhaust gases. For example, the widely used diesel fuel is a significant source of nitrogen oxides (NOx) and particulate matter (PM). To reduce the content NOx and PM, different oxygenated compounds were mixed into a mineral diesel available at the pump, and their effect on the composition of exhaust gas emissions was measured using a one-cylinder diesel generator. In this setup, adding methanol gave the best relative results. The addition of 2000 ppm of methanol decreased the content of NO by 56%, 2000 ppm of isopropanol decreased NO2 by 50%, and 2000 ppm ethanol decreased PM by 63%. An interesting question is whether it is possible to reduce the impact of hazardous components in the exhaust gas even more by adding oxygenates to biodiesels. In this article, alcohol is added to biodiesel in order to establish the impact on PM and NOx concentrations in the exhaust gases. Adding methanol, ethanol, and isopropanol at concentrations of 2000 ppm and 4000 ppm did not improve NOx emissions. The best results were using pure RME for a low NO content, pure diesel for a low NO2 content, and for PM there were no statistically significant differences.

“…According to the Paris agreement and also a report released by Intergovernmental Panel on Climate Change (IPCC) [3], a large portion of carbon dioxide is sourced from the industrial sector and transportation showing that the current pathway of combustion of fossil fuels will not be sustainable [4]. Combustion of fossil fuels releases air pollutants such as NOx, CO2 [5], and particulate matter (PM2.5) [6], which results in air pollution, environmental damage and intensification of global warming. Therefore, there is a need to further develop energy production systems together with seeking alternative energy resources such as renewable energy to replace fossil fuels and avoid pollutions associated with their combustion.…”
