Exhibit 31.1

I, William P. Long, certify that:

         1.  I  have  reviewed  this  annual  report  on  Form  10-K  of  Altair
Nanotechnologies Inc.;

         2. Based on my  knowledge,  this  annual  report  does not  contain any
untrue  statement of a material fact or omit to state a material fact  necessary
to make the  statements  made,  in light of the  circumstances  under which such
statements  were made, not misleading with respect to the period covered by this
report;

         3. Based on my knowledge, the financial statements, and other financial
information  included  in this annual  report,  fairly  present in all  material
respects the financial  condition,  results of operations  and cash flows of the
registrant as of, and for, the periods presented in this report;

         4. The registrant's other certifying officers and I are responsible for
establishing and maintaining  disclosure  controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and we have:

                  (a)  Designed  such  disclosure  controls and  procedures,  or
                  caused such disclosure  controls and procedures to be designed
                  under our  supervision,  to ensure that  material  information
                  relating  to  the  registrant,   including  its   consolidated
                  subsidiaries,  is made  known  to us by  others  within  those
                  entities,  particularly during the period in which this report
                  is being prepared;

                  (b) Evaluated the effectiveness of the registrant's disclosure
                  controls  and  procedures  and  presented  in this  report our
                  conclusions about the effectiveness of the disclosure controls
                  and  procedures,  as of the end of the period  covered by this
                  report based on such evaluation; and

                  (c)  Disclosed  in this report any change in the  registrant's
                  internal control over financial reporting that occurred during
                  the registrant's  most recent fiscal quarter (the registrant's
                  fourth  fiscal  quarter in the case of an annual  report) that
                  has materially affected, or is reasonably likely to materially
                  affect,  the  registrant's  internal  control  over  financial
                  reporting; and

         5. The  registrant's  other  certifying  officers and I have disclosed,
based on our most recent evaluation,  to the registrant's auditors and the audit
committee  of  registrant's  board  of  directors  (or  persons  performing  the
equivalent functions):

                  (a) All significant  deficiencies  and material  weaknesses in
                  the design or  operation of internal  control  over  financial
                  reporting which are reasonably  likely to adversely affect the
                  registrant's ability to record, process,  summarize and report
                  financial information; and

                  (b)  Any  fraud,  whether  or  not  material,   that  involves
                  management or other  employees who have a significant  role in
                  the registrant's internal control over financial reporting.
