The lesson we learnt in the petroleum era is: global economy cannot be sustainably prosperous without balancing the high demand in energy resource and the serious environmental issue. According to the solar market research and analysis, the photovoltaic solar (PV) industry created $38.5 billion in revenues globally in 2009. The market size of solar energy increases with the rate of 30% annually. Great efforts have been attempted for utilizing solar energy and minimizing and avoiding the CO2 emission in the world for a decade. Is it possible to develop a device to be able to solve two challenges? The goal of this project is to work with Saint Jean Carbon Inc. (SJC) to develop carbon-based quantum dots (C-dots) for multi-applications, especially in photo-induced electron transfer devices and CO2 capture. In this two-year collaborative research project, first we will develop a time-efficient process to produce C-dots-based nanosystems with tunable optical properties; and to incorporate C-dots onto ZnO nanorods for harvesting solar energy to obtain efficient photoinduced electron transfer. In addition, this project will design and develop a suitable surface modification to conjugate enayme on the C-dots-based nanosystem for efficient CO2 capture. This project by applying nanomaterials and biomaterials aims at developing a high efficient PV device with the capacity for CO2 capture. Two trainees will be involved in this project to gain the knowledge and skills on development of nanomaterials and environmentally-friendly devices. The successful research project will help Canadian companies to open up more potential areas of applications, to broaden the horizon of carbon-based products, and to boost Canadian Eco-friendly economy.

我们从石油时代得到的教训是：如果不平衡对能源的高需求和严重的环境问题，全球经济就不可能持续繁荣。根据太阳能市场研究和分析，2009年光伏太阳能(PV)行业在全球创造了385亿美元的收入。太阳能市场规模以每年30%的速度增长。近十年来，世界各国都在努力利用太阳能，最大限度地减少和避免二氧化碳排放。有没有可能开发出一种能够解决两个挑战的设备？该项目的目标是与Saint Jean Carbon Inc.(SJC)合作开发用于多种应用的碳基量子点(C点)，特别是在光致电子转移设备和二氧化碳捕获方面。在这个为期两年的合作研究项目中，我们首先将开发一种省时的工艺来制备具有可调光学性质的基于C-点的纳米系统；并将C-点掺入到氧化锌纳米棒中以获取太阳能，以获得高效的光致电子转移。此外，该项目还将设计和开发一种合适的表面修饰，以连接基于C-DOTS的纳米系统上的酶，以实现高效的二氧化碳捕获。该项目通过应用纳米材料和生物材料，旨在开发一种具有二氧化碳捕获能力的高效光伏器件。两名学员将参与这一项目，以获得纳米材料和环保设备开发方面的知识和技能。该研究项目的成功将有助于加拿大企业开拓更多潜在的应用领域，拓宽碳基产品的视野，促进加拿大生态友好型经济。
