“…As such, researchers started to study nonnoble metals or transition metals such as Co, Ni, Bi, and Fe as they have shown promising results in noble metals. For example, Deng et al 135 synthesized a 0D Ni/2D N‐doped g‐C 3 N 4 heterostructure with different volumes of a Ni‐containing solution using the photodeposition method in the presence of TEOA (Figure 7A). The role of TEOA in this process is to facilitate electron transfer to the N‐doped g‐C 3 N 4 surface, which is then captured by Ni ions to form Ni NPs that will act as the nucleation center.…”

Green energy generation is an indispensable task to concurrently resolve fossil fuel depletion and environmental issues to align with the global goals of achieving carbon neutrality. Photocatalysis, a process that transforms solar energy into clean fuels through a photocatalyst, represents a felicitous direction toward sustainability. Eco-rich metal-free graphitic carbon nitride (g-C 3 N 4 ) is profiled as an attractive photocatalyst due to its fascinating properties, including excellent chemical and thermal stability, moderate band gap, visible light-active nature, and ease of fabrication. Nonetheless, the shortcomings of g-C 3 N 4 include fast charge recombination and limited surface-active sites, which adversely affect photocatalytic reactions. Among the modification strategies, point-to-face contact engineering of 2D g-C 3 N 4 with 0D nanomaterials represents an innovative and promising synergy owing to several intriguing attributes such as the high specific surface area, short effective charge-transfer pathways, and quantum confinement effects. This review introduces recent advances achieved in experimental and computational studies on the interfacial design of 0D nanostructures on 2D g-C 3 N 4 in the construction of point-to-face heterojunction interfaces. Notably, 0D materials such as metals, metal oxides, metal sulfides, metal selenides, metal phosphides, and nonmetals on g-C 3 N 4 with different charge-transfer mechanisms are systematically discussed along with controllable synthesis strategies. The applications of 0D/2D g-C 3 N 4 -based photocatalysts are focused on

“…In addition to reaction dependence of the identity and quantity of the PS, experiments varying the WRC identity and concentration are vital to understanding photocatalytic water reduction. Much like PSs, various classes of WRCs are availableincluding noble metal complexes, noble metal colloids, , non-noble metal complexes, ,, non-noble metal colloids and a variety of species which are molecularly tethered to their respective PSs. , Classic work in the field has utilized Pt and Pd colloidal catalysts, which remain some of the most active known catalysts. A great bulk of research approaches the removal of these expensive and rare metals, which has been greatly accelerated with the advent of parallel experimentation.…”

Photocatalytic hydrogen (H2) evolution, particularly though water reduction, presents an enticing alternative to current fossil fuel intensive methods of hydrogen production. While this field has been active for decades and advances have been made, it has been limited to serial experimentation due to the solar-mimicking lamps used and data collection techniques. With the democratization of machine and instrument design through the ever-decreasing prices of computers and sensing equipment, paired with the availability of high-power light emitting diodes (LEDs) as viable replacement light sources, reactor design has seen significant changes in recent years. After the advent of the first LED-illuminated parallel reactors for gas evolving photocatalytic reactions, a host of research groups around the world have matched the design and used their own creative means of studying H2 evolving reactions in parallel. Here we report select cases of research utilizing parallelized reactors for light-driven H2 evolution, highlighting the benefits of parallel and high-throughput experimentation. Lastly, changes to reactor design and sensing methodology, specifically how colorimetric measurement enabled the development of a 108-well parallelized reactor, are described, and these state-of-the-art reactors are compared to alternative, nonparallelized approaches using serial, robotic automation.

“…In addition, introducing other non-metal elements are also effective strategies in promoting the photocatalytic property ( Deng et al, 2019 ; Li et al, 2021b ; Li et al, 2021c ; Liu et al, 2021 ; Yan et al, 2022 ). For instance, carbon (C) self-doped g-C 3 N 4 was prepared via a combined method of melamine-cyanuric acid complex supramolecular pre-assembly and solvothermal pre-treatment ( Li et al, 2021b ).…”
