摘要

将玉米秸秆加入Pt/TiO

的悬浊液中，在紫外光照射下实现了光催化分解水制氢速率的提升。通过SEM、XRD、FT-IR和TGA对玉米秸秆在光催化反应后的结构特征的变化进行了表征和分析讨论。通过单因素实验和正交实验研究了辐照时间、玉米秸秆颗粒浓度、秸秆颗粒粒径和催化剂浓度对氢气产率及产氢量的影响。实验结果表明：催化剂浓度和秸秆颗粒浓度对产氢的影响较大。产氢量随着催化剂浓度的增加先增后减，在催化剂浓度为4

Abstract

In this study

addition of corn stover to the water suspension of Pt/TiO

significantly improved H

evolution from water splitting under UV light. The structural characteristics of corn stover after photocatalytic reaction were characterized by SEM

XRD

FT-IR and TGA. The effects of irradiation time

corn stover particle concentration

stover particle size and catalyst concentration on hydrogen production were studied by single factor experiment and orthogonal experiment. The results show that the catalyst concentration and corn stover particle concentration have a greater impact on hydrogen production. Under the experimental conditions in this paper

the hydrogen production rate and hydrogen yield increase first and then decrease with the increase of catalyst concentration

and the catalyst concentration is 4×10

-3

g/ml to 6×10

-3

g/ml. The highest hydrogen yield is obtained. When the concentration of stover granules is more than 0.5×10

-3

g/ml

the hydrogen production rate decreases with the increase of stover granule concentration. And the hydrogen yield shows different patterns of change with the irradiation time in different stover granule concentration. However

too small corn stover particle size will have a negative impact of hydrogen production.
