“…These characteristics are due to the intersection of a nitrogen atom to the transition metal, which significantly reduces the d-band and increases the d state electron density up to the Fermi level that makes the electronic structure of TMN behave like that of noble metals such as Pt and Pd . In addition to the metallic conductivity, TMN has very high corrosion resistance toward aqueous and nonaqueous electrolytes, putting forward metal nitrides as potential candidates to replace noble platinum CE for DSSCs. TMNs such as TiN, VN, MoN, Ni 3 N, NbN, WN, and W 2 N are tested as CEs for DSSC. Our previous work on DSSC also demonstrated the successful synthesis of different nanostructures of VN and Mo 2 N as efficient CEs for DSSCs. Among different metal nitrides, titanium nitride is low cost, is electrochemically stable, and shows excellent electrocatalytic activity in triiodide reduction. ,, The reports on TiN electrodes with different nanostructures and composites have demonstrated effective catalytic activity toward the iodide/triiodide electrolyte and photocurrent voltage conversion efficiencies comparable to that of conventional platinum; importantly, TiN is the one among the first used metal compound as an alternate to the Pt CE in DSSCs. , Jiang et al have studied the TiN nanotube array prepared by anodization of a Ti foil substrate with subsequent nitridation in a ammonia atmosphere as the CE for DSSCs and reported with the power conversion efficiency (PCE) of 7.73% comparable to FTO/Pt with a PCE of 7.45% .…”

“…Being an interstitial compound, TMNs possess metallic conductivity, high melting point, and high hardness. [379] Thus, TMNs are widely employed as catalysts, [380][381][382] semiconductors, [383] sensors, [384] electrodes for supercapacitors, [385][386][387] and batteries. [386,388] Notably, the formation of metal nitrides alters the nature of the d band on the parent metal resulting in the catalytic properties that are different from those of parent metal but identical to those of noble metals.…”

“…The CP’s contraction mechanism (reduction reaction) is similar to the expansion mechanism (oxidation reaction) [ 106 ]. In addition, CPs can also be used to replace alkaline metal as biosensors, such as for non-enzymatic glucose sensors, hydrogen peroxide (H 2 O 2 ) sensors, and dissolved oxygen sensors [ 107 ]. Recently, CPs like PANI was reported to have antibacterial properties through a disruption process against the native surface charge of bacterial cells [ 108 ].…”
