Tóm tắt

Trong bài báo này, chúng tôi báo cáo về các hạt nano MnS, CdS và MnS/CdS được chế tạo bằng phương pháp kết tủa. Các hạt tổng hợp được đặc trưng bằng kính hiển vi điện tử quét, nhiễu xạ tia X, quang phổ phản xạ khuếch tán UV, quang phát quang, quang phổ điện tử tia X và kỹ thuật photoelectrochemical. Sự kết hợp composite MnS/CdS đã nâng cao các tính chất quang học, quang xúc tác và quang điện tử của các mẫu vật. Hiệu suất quang xúc tác của các mẫu vật được đánh giá dưới sự chiếu sáng của ánh sáng nhìn thấy. Hoạt động quang điện của tất cả các mẫu cũng đã được điều tra. Các hợp chất MnS/CdS đã được phát hiện là những chất xúc tác quang hiệu quả trong điều kiện ánh sáng nhìn thấy. Hiệu suất quang xúc tác nâng cao của các hợp chất này được cho là nhờ vào cấu trúc thiếu khuyết, mật độ electron cao của CdS và sự ức chế của cặp electron/lỗ trống cũng như hàm lượng tối ưu của CdS trong hệ composite. Các hợp chất MnS/CdS cần được đánh giá đối với hoạt động quang xúc tác và quang điện hóa trong phạm vi ánh sáng nhìn thấy rộng hơn.
