Analysis of Research Hotspots and Development Trends of Iron-modified Biochar Based on Bibliometrics
摘要
Abstract
As an emerging functional composite material,iron-modified biochar combines the structural characteristics of biochar with the high redox activity of iron,exhibiting excellent catalytic performance and environmental stability.This ma-terial has attracted extensive attention in the fields of wastewater treatment,soil and water environment remediation in re-cent years.This study applies CiteSpace software to perform a bibliometric analysis with visualization of iron-modified bio-char research dynamics,based on the Web of Science Core Collection dataset,aiming to comprehensively understand the research hotspots and development trends of iron-modified biochar.The results reveal a consistent increase in publications on iron-modified biochar since 2011,with particularly rapid growth observed over the past five years.China dominates this field,producing the highest number of publications.Zero-valent iron modification is the most extensively studied approach,while magnetic properties represent the most investigated characteristics of iron-modified biochar.Its functionality primarily relies on three mechanisms:adsorption,catalytic activity,and serving as a reaction carrier.Research hotspots have shifted from the initial focus on phosphate removal in sewage to various fields such as wastewater treatment,soil and water envi-ronment remediation,and bioenergy production.Concurrently,research attention has transitioned from simple effects to in-trinsic mechanisms,special function enhancement,and low-cost preparation methods.Future research should continue to deepen the understanding of the functional mechanisms and key characteristics strengthening pathways of iron-modified bio-char,expand its application areas,explore sustainable preparation strategies from a functional materials development per-spective,and advance the large-scale,green,and low-cost application of this material.关键词
