“…The principle of the concept consists in the concentration and recirculation of NO x into the combustion chamber of the engine where they are decomposed thermally [213]. Because thermal decomposition depends on NO x concentration, a high performance of the adsorbent material is the key for the success of the SNR concept [202,214].…”

“…Many catalytic processes for the transformation of nitrogen gases (e.g., NO and NO 2 ) into nitrogen (N 2 ), oxygen (O 2 ), or nitrate (NO 3 − ) have been established [249,250]. An ideal NOx conversion catalyst transforms NOx gases at lower-temperature [251]. TiO 2 is one of the leading catalysts for the catalytic conversion of NOx gases into nitrous oxide (N 2 O) and N 2 [252,253].…”

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.

“…On the other hand, technical solutions existing for the optimal compromise in removal of NOx/PM [19], by exhaust gas recirculation (EGR), are not able to achieve the requirements of Euro 6. In fact, in these systems, reduction of PM means eventually an increment of NOx and viceversa [20].…”
