Dry reforming of hydrocarbons (DRH) is a pro-environmental method for syngas production. It owes its pro-environmental character to the use of carbon dioxide, which is one of the main greenhouse gases. Currently used nickel catalysts on oxide supports suffer from rapid deactivation due to sintering of active metal particles or the deposition of carbon deposits blocking the flow of gases through the reaction tube. In this view, new alternative catalysts are highly sought after. Transition metal carbides (TMCs) can potentially replace traditional nickel catalysts due to their stability and activity in DR processes. The catalytic activity of carbides results from the synthesis-dependent structural properties of carbides. In this respect, this review presents the most important methods of titanium, molybdenum, and tungsten carbide synthesis and the influence of their properties on activity in catalyzing the reaction of methane with carbon dioxide.

“…In oxide based counter electrodes, various transition metal oxides are attempted to study as a counter electrode for DSSC [14][15][16][17][18][19]. Of these, molybdenum trioxide (MoO 3 ) is one of the renowned oxide material, commonly used for versatile applications such as in energy storage, catalysis, electrochromics, photochromics, thermochromics, display materials, sensors [20][21][22][23][24][25][26]. It also exhibits good electrocatalytic activity, hence it could be the potential candidate for CE in DSSC.…”

Owing to increase in energy demands and depletion in fossil fuels, solar energy conversion is the reliable and sustainable one for future. Among the solar energy conversion techniques, dye-sensitized solar cells (DSSC) have received much attention due to their ease of fabrication, cost-effectiveness, reliable and high proficiency in converting solar energy. The commercialization of DSSC is still hindered by usage of expensive materials like platinum counter electrodes. Therefore, researchers are focusing on developing low-cost and earth abundant alternatives. The present work involves hydrothermal synthesis of molybdenum trioxide (MoO 3) at various temperature ranges such as 400, 500, 600 and 700 °C and several other characterizations through various analytical techniques. On increasing the temperature range, the MoO 3 forms nanorod like structure. The synthesized materials are employed as counter electrode in DSSC, showed enhanced power conversion efficiency (PCE) on increasing the calcination temperature range. The maximum PCE of 4.13% is obtained for MoO 3 calcined at 600 °C, which is highly comparable with the high cost platinum CE based DSSC.

“…Unfortunately, since Pt is expensive, employing a cheaper substitute becomes a stringent requirement. So far, there are cheaper alternative materials that can rival with Pt in terms of electrocatalytic performance such as nitrides [3], sulfides [4], carbides [5], and carbon allotropes. Various types of carbons that can function well as CE catalysts include graphites, carbon nanotubes, graphenes, reduced graphene oxides, activated carbons, carbon blacks, and biomass-derived charcoals (biochars) [6][7][8][9][10][11][12][13].…”

Carbon derived from hair is interesting because it has good electrocatalytic activity due to the existence of innate heteroatom dopants especially nitrogen and sulfur. In this study, a carbon catalyst containing high nitrogen contents (9.47 at.%) was fabricated without using any harsh chemicals. Moreover, the carbonization temperature was only 700°C. Carbonized hair/ PEDOT:PSS composites (C x P) with varied carbon contents from x = 0.2 to 0.8 g were tested as a counter electrode (CE) for a dye-sensitized solar cell (DSSC). This type of DSSC CE has scarcely been investigated. A DSSC with a C 0.6 P CE provides the best efficiency (6.54 ± 0.11%) among all composite CEs because it has a high fill factor (FF) and a high short-circuit current density (J sc ). The efficiency of DSSC with C 0.6 P CE is lower than Pt's (7.29 ± 0.01%) since the Pt-based DSSC has higher FF and J sc values. However, C 0.6 P is still promising as a DSSC CE since it is more cost-effective than Pt.
