The global energy crisis and environmental problems have become two unprecedented challenges.Semi-conductor photocatalysis offers a promising strategy to solve them,while its practical application requires advanced photocatalytic materials.In recent years,one-dimensional(1D)alkali-metal hexatitanate(AHT)photocatalysts have attracted considerable attention in energy and environmental fields due to their high chemical stability,excellent photoactivity,unique ion-exchange,environment-friendly,and cost-effective properties.In this review,we firstly introduce the basic properties of AHT including crystal and electronic band structure,photoactivity,and structure-property-performance relationship.Secondly,the recent ad-vances in synthesis and modification strategies of 1D AHT photocatalysts are summarized thoughtfully,followed by a comprehensive discussion on their various environmental and energy applications,includ-ing pollutant degradation,H2 generation,and CO2 reduction.Finally,the key challenges and prospects are also highlighted for the development of high-performance 1D AHT-based photocatalysts for practi-cal applications.We hope that this review will shed some light on the rational design of 1D Ti-O-based nanomaterials for efficient environmental remediation and solar fuel production.
