This　study　employs　a　Fenton-like　catalyst　incorporating　dual　transition　metals　and　attapulgite　to　generate　diverse　Lewis　acid　sites,　thereby　extending　the　pH　applicability　range　for　organic　pollutants　degradation.　Optimization　of　degradation　conditions　resulted　in　total　organic　carbon　(TOC)　degradation　rates　of　85　%,　78　%,　and　79　%　in　landfill　leachate　nanofiltration　concentrates　at　pH　of　3,　7,　and　10,　respectively.　The　catalyst＇s　diverse　Lewis　acid　sites　create　electron-donating　and　electron-withdrawing　abilities　that　facilitate　effective　electron　transfer　with　organic　pollutants　and　oxidants,　extending　its　pH　range.　UV–vis　and　fluorescence　spectra　confirm　the　catalyst　system＇s　strong　environmental　remediation　capabilities,　offering　a　novel　strategy　for　heterogenous　Fenton-like　reactions　in　environmental　cleanup.　©　2025
