“…Currently, TiO 2 NPs can be synthesized by hydrothermal, microwave irradiation, and sol–gel methods, 7 but these methods require hazardous chemicals and extreme reaction conditions, which are time-consuming, energy-wasting, and environmentally unfriendly. 8 Therefore, plant- and microbial-mediated synthesis of NPs is of increasing interest to researchers. Synthesis using plant extracts is generally green, safe, and cost-effective, and by-products are less toxic and easy to handle, due to the antioxidants and secondary metabolites contained in the extracts that act as bio-capping and reducing agents to stabilize the formation of NP crystals.…”

“…On the other hand, the non‐edible (e. g., Jatropha, karanja, polanga, royna, and neem etc.) are most suitable candidates for biodiesel production as they are not consumed by humans, and most of source seeds are disposed in open environment as there are no specific regulations and practices for such waste disposal [17] . For example, the waste animal fats are appealing resources of non‐edible oils and exposed openly which can cause serious health related problems and environmental issues [18] .…”

Biodiesel produced from different edible and non‐edible feedstocks is a viable alternative option for fueling a combustion engine. However, the widespread use of edible sources for biodiesel production may lead to food versus fuel controversy. Oil from non‐edible feedstock is best possible solution for problems that inhibits biodiesel production on commercial scale. This study presents the potential of different non‐edible feedstock for biodiesel production. Several aspects such as extraction technologies used for extracting oil from non‐edible sources and biodiesel production pathways from non‐edible feedstocks are discussed. The quality of biodiesel should be assured before its commercialization by different physical and chemical characterization techniques are used. In particular, the emission comparison of biodiesel derived from the different non‐edible feedstocks is discussed. Based on this study, the non‐edible feedstocks have the potential to produce biodiesel but still it has a long way to go. This is due to non‐edible feedstock is in the R&D phase and needs more research to eliminate additional treatment steps compared to edible feedstock for economic aspects. Furthermore, there has been a trade off in emission properties of biodiesels produced from non‐edible feedstocks which must be removed or evaluated for pilot scale investigations before commercialization.

“…Titanium dioxide (TiO 2 ), is a widely used n-type semiconductor known for its biocompatibility, chemical stability, abundance, and impressive photocatalytic properties. , Recently, it is reported that TiO 2 with oxygen defects and interface-engineered heterojunctions have good electrocatalytic activity for the NRR. Meanwhile, heteroatom doping is a promising strategy for improving nitrogen reduction performance in the electrocatalytic NRR due to its ability to regulate the electronic structure and enhance nitrogen adsorption capacity .…”

Titanium dioxide has recently received a lot of attention as a potential catalyst for the electrochemical nitrogen reduction reaction (NRR). However, the effect of surface reconstruction of titanium dioxide during the phase transition on electrocatalysis has attracted little attention. Here, we develop a facile one-pot phase-transition engineering strategy to implant defects in iron-doped titanium dioxide. Our engineering strategy shows advantages including a simple synthesis process, phasetransition efficiency, cost-effective materials, and scalability. The experimental results and density functional theory (DFT) calculations demonstrate that surface oxygen vacancies and doping Fe atoms play crucial roles as potential electrocatalytic sites for the NRR on Fe−TiO 2 catalysts, which enables efficient inhibition of the hydrogen evolution reaction (HER). A high NH 3 yield of 30.9 ± 0.4 μg h −1 mg cat.−1 and a Faradaic efficiency (FE) of 40.4 ± 1.1% at −0.4 V vs reversible hydrogen electrode are obtained for the NRR, outperforming most Ti-based catalysts reported previously. The formation and electrocatalytic NRR properties of Mn−TiO 2 , Co−TiO 2 , Ni−TiO 2 , and Cu−TiO 2 are also verified.
