Porous Materials Embedded Mixed-Matrix Membranes for Precious Metal Recycling

This graphic illustrates the hands-on laboratory experience students will gain, showcasing the use of advanced porous materials (MOFs and COFs) to selectively capture and recover precious metals from electronic waste streams.

Learn sustainable materials design and circular economy concepts through hands-on research in metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and polymer mixed-matrix membranes (MMMs).

Project description

This interdisciplinary project introduces undergraduate students to sustainable materials design and circular economy concepts through hands-on research in metal–organic frameworks (MOFs), covalent organic frameworks (COFs), and polymer mixed-matrix membranes (MMMs). The research focuses on embedding porous, functional frameworks into polymer matrices to create selective membranes for recovering precious metals (Au, Pd, Pt, Ag) from electronic and catalytic waste streams. Students will learn how to synthesize porous materials, fabricate membranes, and evaluate their separation performance, contributing to new approaches for resource recovery, environmental remediation, and materials sustainability. This project aligns with the goals of the Undergraduate Research and Creative Activity Program by offering a structured, faculty‑mentored research experience that emphasizes scientific inquiry, interdisciplinary learning, and professional skill development rather than hourly lab assistance.

Project outcome

Engage in professional communication by producing a research poster and presentation for the UB Celebration of Student Academic Excellence or the Undergraduate Research Symposium, as well as a short report or manuscript draft suitable for ACS or MRS submission.

Learning outcomes

  • Learn MOF/COF synthesis, membrane fabrication and processing(incorporating porous fillers into polymer supports), and materials characterization(PXRD, BET, FTIR, SEM).
  • Apply chemistry and engineering principles and perform separation and adsorption tests with model metal-ion solutions (Au³⁺, Pd²⁺, Pt⁴⁺) to real-world sustainability challenges.
  • Analyze structure–property relationships between pore chemistry and ion selectivity and develop experimental design, data interpretation, and scientific writing skills.
  • Strengthen abilities in team collaboration, problem solving, and safe lab practice.
  • Understand how porous materials enable selective ion transport and resource recovery.
  • Improve oral and visual communication through presentations and reflective writing.
  • Build professional confidence and a clearer pathway toward graduate study or industry research.
