Study on the effect of alkali photocatalytic pretreatment on enzymatic saccharification of corn stover
The article focuses on corn stover as the research subject and prepares black titanium dioxide(R-TiO2)photocatalyst using the sodium borohydride reduction method.Through comparisons of different pretreatment results,the alkali photocatalytic pretreatment technology was selected.With the yield of reducing sugar and the main components of corn stalks as evaluation indicators,the study explores the impact of various factors,including photocatalyst concentration,reaction time,H2O2 concentration,and NaOH concentration,on the pretreatment effectiveness.The FT-IR,XRD,and SEM analyses show that,compared with other pretreatment methods,the physical properties and microstructure of corn stover undergo significant changes after alkaline photocatalytic pretreatment,the lignin removal rate is effectively improved is effectively improved,which favors the subsequent enzymatic hydrolysis of corn stover.
