Title: One-Step Synthesis of Nb₂O₅/C/Nb₂C (MXene) Composites and Their Use as Photocatalysts for Hydrogen Evolution

Abstract

Abstract Hydrogen production through facile photocatalytic water splitting is regarded as a promising strategy to solve global energy problems. Transition‐metal carbides (MXenes) have recently drawn attention as potential co‐catalyst candidates for photocatalysts. Here, we report niobium pentoxide/carbon/niobium carbide (MXene) hybrid materials (Nb ₂ O ₅ /C/Nb ₂ C) as photocatalysts for hydrogen evolution from water splitting. The Nb ₂ O ₅ /C/Nb ₂ C composites were synthesized by one‐step CO ₂ oxidation of Nb ₂ CT _x . Nb ₂ O ₅ grew homogeneously on Nb ₂ C after mild oxidation, during which some amorphous carbon was also formed. With an optimized oxidation time of 1.0 h, Nb ₂ O ₅ /C/Nb ₂ C showed the highest hydrogen generation rate (7.81 μmol h ⁻¹ g _cat ⁻¹ ), a value that was four times higher than that of pure Nb ₂ O ₅ . The enhanced performance of Nb ₂ O ₅ /C/Nb ₂ C was attributed to intimate contact between Nb ₂ O ₅ and conductive Nb ₂ C and the separation of photogenerated charge carriers at the Nb ₂ O ₅ /Nb ₂ C interface; the results presented herein show that transition‐metal carbide are promising co‐catalysts for photocatalytic hydrogenmore » production.« less

Titania Composites with 2 D Transition Metal Carbides as Photocatalysts for Hydrogen Production under Visible-Light Irradiation

Journal Article Wang, Hui ; Peng, Rui ; Hood, Zachary D. ; ... - ChemSusChem

Abstract MXenes, a family of two‐dimensional transition‐metal carbides, were successfully demonstrated as co‐catalysts with rutile TiO ₂ for visible‐light‐induced solar hydrogen production from water splitting. The physicochemical properties of Ti ₃ C ₂ T _x MXene coupled with TiO ₂ were investigated by a variety of characterization techniques. The effect of the Ti ₃ C ₂ T _x loading on the photocatalytic performance of the TiO ₂ /Ti ₃ C ₂ T _x composites was elucidated. With an optimized Ti ₃ C ₂ T _x content of 5 wt %, the TiO ₂ /Timore »« less

Monolayer Ti₃C₂T_x as an Effective Co-catalyst for Enhanced Photocatalytic Hydrogen Production over TiO₂

Journal Article Su, Tongming ; Hood, Zachary D. ; Naguib, Michael ; ... - ACS Applied Energy Materials

Titanium dioxide (TiO₂) represents a promising candidate for hydrogen production via photocatalysis. Yet, its large bandgap and fast charge recombination limits its efficiency. To overcome this limitation, we explored in this work two-dimensional titanium carbide MXene, Ti₃C₂T_x (T_x = O, OH, F), as feasible co-catalysts for hydrogen production with TiO₂ as the photocatalyst. We synthesized a series of Ti₃C₂T_x/TiO₂ composite photocatalysts with monolayer Ti₃C₂T_x as the co-catalyst to improve the separation of photoinduced electrons and holes. The physicochemical properties of the Ti₃C₂T_x/TiO₂ composites were investigated by a variety of characterization techniques, and the effect of the monolayer Ti₃C₂T_x on themore »« less

Effect of pinholes in Nb₄C₃ MXene sheets on its electrochemical behavior in aqueous electrolytes

Journal Article Zhao, Shuangshuang ; Wang, Xuehang ; Kurra, Narendra ; ... - Electrochemistry Communications

Two-dimensional (2D) niobium carbide, Nb₄C₃T_x (T_x: O, OH, and F), a representative member of the 43 MXene structural motif, has shown promising electrochemical performance in acidic electrolytes. The capacitive performance of Nb₄C₃T_x in neutral aqueous electrolytes has been reported as moderate, but little effort has been made to improve it. In this paper, we report a method to introduce nanopores (pinholes) in Nb₄C₃T_x MXene flakes by adjusting the etching time. The pinholes generated during the etching process improve ion diffusion pathways, which are otherwise hindered by the restacking of the 2D flakes. The “holey Nb₄C₃T_x” shows a 50 % improvedmore »« less

A Current Perspective on Photocatalysis

Journal Article Fujita, E ; Muckerman, J T ; Domen, K - ChemSusChem

The efficient conversion of solar photons into solar electricity and solar fuels is one of the most important scientific challenges of this century owing to dwindling fossil fuel reserves and the need for clean energy. While research in the direct conversion of solar energy to electricity in the areas of low-cost photovoltaic (PV) systems based on all-inorganic semiconductors, dye-sensitized solar cells, organic, and molecular PV is more technically advanced than its direct conversion to fuels, electricity may not be the ultimate primary solar energy conversion choice owing to the intermittence of solar radiation, the considerable energy loss during transmission, themore »« less

Electrical and Elastic Properties of Individual Single-Layer Nb₄C₃T_x MXene Flakes

Journal Article Lipatov, Alexey ; Alhabeb, Mohamed ; Lu, Haidong ; ... - Advanced Electronic Materials

2D carbides and nitrides (MXenes) are widely recognized for their exceptional promise for numerous applications. However, physical property measurements of their individual monolayers remain very limited despite their importance for revealing the intrinsic physical properties of MXenes. The first mechanical and electrical measurements of individual single-layer flakes of Nb₄C₃T_x MXene, which are prepared via an improved synthetic method are reported. Characterization of field-effect transistor devices based on individual single-layer Nb₄C₃T_x flakes shows an electrical conductivity of 1024 ± 165 S cm_-1, which is two orders of magnitude higher than the previously reported values for bulk Nb₄C₃T_x assemblies, and an electronmore »« less
