Nitrogen Oxides (NOx) pollutants in the air lead to many issues of varying severity. The particles interact with water, oxygen, and other chemicals to form acid rain and aggravate the respiratory tract in higher concentrations, putting people with respiratory diseases at risk (Basic Information about NO2 2016). There have been many efforts to reduce the amount of NOx pollution, such as switching to renewable energy sources and photocatalytic pollutant degradation. Out of the reactive solutions, photocatalysis has achieved significant results in laboratory tests (Lasa et al., 2005). However, more studies must be conducted in order to allow for more durable, practical, and long term photocatalytic solutions. This study aims to explore the longevity and efficacy of a Titanium Dioxide-Graphene nanocomposite (TiO2-GR) in an epoxy asphalt that can be used on roads in city environments to mitigate the effects of NOx and other pollutants where they are most concentrated.


Abstracts must effectively summarize the paper so that readers can quickly determine its relevance to the topic that they are searching for. For the purposes of writing a proposal, this author does well in concisely representing certain parts of the writing. She includes a bit from all the important components, including the rationale for the proposal, the past works that have influenced the decisions in the making of the proposal, and the goals of the study. However, to make better use of the 150 word limit for Envision, she could have made the discussion of the issue that the study tries to solve more concise and instead added a sentence about the methods that the study uses to quickly demonstrate the innovation behind the proposal and the obstacles that might be met with the proposed methods in order to show the feasibility. As an informative abstract, the writer does well in showing the necessity for the proposal but could do a better job in introducing the proposal itself by discussing the methods.
