Summary Photocatalytic ammonia synthesis, as a suitable alternative to traditional Haber‐Bosch artificial nitrogen reduction process, has aroused widespread interest. Graphitic carbon nitride (g‐C3N4) has emerged as an attractive metal‐free photocatalyst, but its development in photocatalytic ammonia synthesis field is greatly shackled to the low photocatalytic activity. In this work, a highly active Fe‐doped tubular graphitic carbon nitride (Fe‐TCN) is reported, which demonstrates transformative performance on photosynthesis of NH3 from N2. Such excellent photocatalytic activity is derived from the incorporation of Fe species as the active sites to efficiently adsorb and activate N2 molecules on the surface of TCN. Simultaneously, surface‐active Fe species are also regarded as the trap sites of electrons, and the concentrated electrons at surface‐active Fe species can significantly improve the NH3 conversion efficiency. Impressively, Fe‐TCN realized a 9.5‐fold enhancement of NH3 production rate with the yield of 647 μmol g−1 h−1 (λ ≥ 420 nm), and the corresponding reaction pathways are also established.

Being one of the foremost enticing and intriguing innovations, heterogeneous photocatalysis has also been used to effectively gather, transform, and conserve sustainable sun‘s radiation for the production of efficient and clean fossil energy as well as a wide range of ecological implications. The generation of solar fuel‐based water splitting and CO2 photoreduction is excellent for generating alternative resources and reducing global warming. Developing an inexpensive photocatalyst can effectively split water into hydrogen (H2), oxygen (O2) sources, and carbon dioxide (CO2) into fuel sources, which is a crucial problem in photocatalysis. The metal‐free g‐C3N4 photocatalyst has a high solar fuel generation potential. This review covers the most recent advancements in g‐C3N4 preparation, including innovative design concepts and new synthesis methods, and novel ideas for expanding the light absorption of pure g‐C3N4 for photocatalytic application. Similarly, the main issue concerning research and prospects in photocatalysts based g‐C3N4 was also discussed. The current dissertation provides an overview of comprehensive understanding of the exploitation of the extraordinary systemic and characteristics, as well as the fabrication processes and uses of g‐C3N4.

Use of MXenes (Ti 3 C 2 T x ), which belongs to the family of two-dimensional transition metal nitrides and carbides by encompassing unique combination of metallic conductivity and hydrophilicity, is receiving tremendous attention, since its discovery as energy material in 2011. Owing to its precursor selective chemical etching, and unique intrinsic characteristics, the MXene surface properties are further classified into highly chemically active compound, which further produced different surface functional groups i. e., oxygen, fluorine or hydroxyl groups. However, the role of surface functional groups doesn't not only have a significant impact onto its electrochemical and hydrophilic characteristics (i. e., ion adsorption/diffusion), but also imparting a noteworthy effect onto its conductivity, work function, electronic structure and properties. Henceforth, such kind of inherent chemical nature, robust electrochemistry and high hydrophilicity ultimately increasing the MXene application as a most propitious material for [a] A
