Cu–N Dopants Boost Electron Transfer and Photooxidation Reactions of Carbon Dots

by Wenting Wu, Liying Zhan, Weiyu Fan, Jizhong Song, Xiaoming Li, Zhongtao Li, Ruiqin Wang, Jinqiang Zhang, Jingtang Zheng, Mingbo Wu, Haibo Zeng

Abstract

The broadband light-absorption ability of carbon dots (CDs) has inspired their application in photocatalysis, however this has been impeded by poor electron transfer inside the CDs. Herein, we report the preparation of Cu–N-doped CDs (Cu-CDs) and investigate both the doping-promoted electron transfer and the performance of the CDs in photooxidation reactions. The Cu–N doping was achieved through a one-step pyrolytic synthesis of CDs with Na2[Cu(EDTA)] as precursor. As confirmed by ESR, FTIR, and X-ray photoelectron spectroscopies, the Cu species chelates with the carbon matrix through Cu–N complexes. As a result of the Cu–N doping, the electron-accepting and -donating abilities were enhanced 2.5 and 1.5 times, and the electric conductivity was also increased to 171.8 μs cm−1. As a result of these enhanced properties, the photocatalytic efficiency of CDs in the photooxidation reaction of 1,4-dihydro-2,6-dimethylpyridine-3,5-dicarboxylate is improved 3.5-fold after CD doping.

Doped dots: Cu–N-doped carbon dots (Cu-CDs) were fabricated by a one-step pyrolytic synthesis using Na2[Cu(EDTA)] as the precursor. Cu–N dopants concomitantly boost the conductivity and the electron-accepting and -donating abilities of the CDs, enhancing the electron-transfer process in the photooxidation of 1,4-dihydro-2,6-dimethylpyridine-3,5-dicarboxylate (see picture; H yellow, N blue, C light blue, O red).

"And no, before you ask, it’s not possible to take time off from work to go to the doctor. Employers..."

“And no, before you ask, it’s not possible to take time off from work to go to the doctor. Employers are often highly resistant to this and aside from the loss of wages, employees may face retaliation for asking for time off to go to their psychiatrists and other mental health care providers. It doesn’t matter if such retaliation is illegal — even if someone could afford to retain an attorney, employers are adroit at finding reasons to explain why, for example, they cut an employee’s hours or moved her to a different shift with fewer tips, leaving her making less at the end of the week.”

Australian skateboarder Oliver Percovich created the non-profit Skateistan in 2007, a grassroots project that connects youth and education through skateboarding in Afghanistan. The organization, which has since grown to an award-winning international NGO, caught the attention of London-based photographer Jessica Fulford-Dobson and inspired her to visit the program in Kabul in 2012—especially after learning 45% of the students were female.

In Afghanistan skateboarding has spread to become the number one sport for women, as they are forbidden to ride bicycles. Soon after arriving and entering the girl’s world, Fulford-Dobson was accepted by the young Afghan skateboarders. She photographed the girls with natural light, helping to expose their personalities through simple portraits. Within the images you can see the girls’ natural confidence, images that capture the subjects both posed and candidly skating through the indoor facility.

“I met so many impressive women and girls in Afghanistan: a teacher as tough and determined as any man; young Afghans in their early twenties who were volunteering at an orphanage and were passionate about being seen as strong and willing to fight for themselves, rather than as victims of circumstance; and girls who were being educated to be leaders in their communities and who were already thinking carefully about their own and their country’s future,” said Fulford-Dobson.

Fulford-Dobson won 2nd prize in the 2014 Taylor Wessing Photographic Portrait Prize with Skate Girl, 2014 (one of the photographs taken while on location in Kabul) and her exhibition Jessica Fulford-Dobson: Skate Girls of Kabul opens at Saatchi Gallery in London on April 15 and runs until April 28, 2015. You can donate to Skateistan’s program in Kabul as well as other cities here. (via feature shoot)
